which triangles do you use COS SIN or TAN?? You can use these relations on any ANGLE. THe sin, cos, and tan are dependent on the angle, it does not matter if the angles are in triangles, or if they are, what kind of triangle. Right triangles are especially helpful when using ...

I recently inquired how to solve a right triangle. I was referred to the Laws o Sine & Cosine quite rightly. I have subsequently found a converter on the net which takes all the headache out of arriving at the correct answers. The thing is I still do not understand how to ...

On a piece of paper draw and label a right triangle using the given sides, solve for the unknown side and write the trigonometric functions for angles A and B, if a=5 and c=7. I already found side b which equals 2 sqrts of 6. Now I need to find the sin A and cos A. I know that...

I have a unit circle graph like the one at the top of a website (do a google search for 'unit circle trig functions' and click the second link, since I can't post links). I need to label the sine, cosine, tangent, secant, cosecant, and cotangent. I found several pictures that ...

They could be log tables, angle tables (sin, cos, tan, cot,sec, csc), statistical tables etc.

I've come across that before.. But the main objective I have difficulty with is when you use the proportion (ex.) angle decimal (after you look it up on the sin, cos, or tan table)/1 and object you are looking for/adjacent What do you do afterward? Or is that it?

I'm having trouble with a concept. I don't understand how the answer was found. 1. Find three other angles, such that cos[beta] = cos . Answers are -25, 335, -335. In my Calc class, the teacher showed it by using a circle, with an angle. Can anyone please help me, via ...

You are using reference angles for this. Where is cosine the same? Cosine in Quadrants I & IV because cosine (referring to the x-coordinate) is positive there. It is negative in Quadrants II & III. Negative angles are simply the angle backtracked from standard position (0 or ...

I am willing to do one just to show you how. Express all functions as sin and cos, for example tan = sin/cos and then remember that sin^2 + cos^2 = 1 4)Which expression is not equivalent to 1? A)sin^2theta+cot^2thetasin^2theta B)sin^2theta/1-costheta -1 C)sec^2theta+tan^2theta...

Let g(x) = sin (cos x^3) Find g ' (x): The choices are a) -3x^2sinx^3cos(cos x^3) b) -3x^2sinx^3sin(cos x^3) c) -3x^2cosx^3sin(cos x^3) d) 3x^2sin^2(cos x^3) I'm not exactly sure where I should start. Should I begin with d/dx of sin? Or do the inside derivative first...and do ...

This is a multiple choice question and then the way you should attack the problem should be different than if you were asked to find the derivative of sin[cos(x^3)] What you do is you use the chain rule, accrding to which the derivative of sin(f(x)) = cos(f(x)) f'(x) Without ...

That depends upon whether the "0" is zero or the Greek symbol theta. Theta is the measure of some angle. Sine, cosine and tangent, which are abbreviated sin, cos and tan, are functions of that angle. They are the ratios of side lengths in a right triangle with one acute angle ...

how do I find the sin, cos, and tan of -60 degrees without using a calculator?

I will do the first one. LS = 1/ sin^2(pi/2 - x) = 1/(sin(pi/2)cosx = cos(pi/2)sinx)^2 = 1/(cosx)^2 RS = 1 + sin^2x/sin^2(pi/2 - x) = 1 + sin^2x/cos^2x --- we did that part in LS = (cos^2 + sin^2x)/cos^2x --- common denominator etc = 1/cos^2x = LS for the second I would change...

sloppy notation. the cot of what, the sin of what? sin, cos, tan, etc are mathematical operators I will use x as the "angle" (Cotx/1-tanx) + (Tanx/1-Cotx) - Tanx - Cotx I usually change everybody to sines and cosines, so ... = (cosx/sinx)/(1 - sinx/cosx) + (sinx/cosx)/(1 - ...

(cos/sin/(1 - sin/cos) + sin/cos/(1-cos/sin) - sin/cos - cos /sin multiply top and bottom of all by sin cos cos^2/(sin cos -sin^2) + sin^2/(sin cos - cos^2) - (sin^2+cos^2)/sin cos cos^2/(sin cos -sin^2) + sin^2/(sin cos - cos^2) - 1 /sin cos cos^2/(sin (cos -sin)) - sin^2/(...

They are trigonomewric identities that are always true, not matter what the angle A is. All can be derived from the Pythagorean theorem of a right angle triangle. If you do not know what sin, cos, tan, sec and cosec mean, I suggest your review your introductory reading ...
