Solve for x to the nearest hundreth and can you explain how you get your answer I don't understand 3^x = 1.295 Your question has nothing to do with trigonometry. You can solve for x by taking the logarithm (to any base) of both sides of the equation. Then x log 3 = log 1.295 x...

determine the trend of each linear function: 1. f(x)= 3x+5 I don't know what you call the "trend" or why you call this a trigonometry question. It is about algebra. The value of the function increases with x at a rate of three times the change in x.

Do you have a calculator? I assume that the log you are talking about is base 10. log(47) = 1.672 log(w) = -2.866 + (2.722)(1.672) = 1.6855 w = 10^1.6855 = 48.5 lb This subject is not trigonometry. It is logarithms. You need a scientific/math hand calculator or a computer to ...

What is Trigonometry?

Trigonometry identities are so hard... I need some help proving these identities: *Oh, and I'm only in grade 11, so the identities we use are quotient identity and Pythagorean identity. sinx/(sinx + cosx) = tanx/(1 + tanx) cos^2x - sin^2x = 2cos^2x - 1 Thanks! Lucy

Well, i tried to see the beauty in trigonometry but to me, it is just too HARD!!!!!!!! There r so many formulae in trigonometry and how to i know which one to use. After i stay in the desk for 15 mins, i just wanna throw this stupid book away. I cant gain anything even i try ...

A weight is oscillating on the end of a spring. The position of the weight relative to the point of equilibrium is given by y=1/12(cos8t-3sin8t), where y is the displacement (in meters) and t is the time (in seconds). Find the times when the weight is at the point of ...

By the way, this is not trigonometry. It is algebra.

This is not a trigonometry question. x^2 + 7x + (7/2)^2 = 11 + (7/2)^2 (x + 7/2)^2 = 23 1/4 x = -7/2 +/- sqrt(93)/2

This is not about trigonometry. x^2 = -121 x = the square root of -121.

This is not calculus. It is basic trigonometry. The kite is 300 sin 57 above her hand. Add 3 feet to that for the height above the ground. Assume the string is 300 feet long, not the kite itself

first use the formula 180/pi to go from radians to degrees, simplified you get 197.6704393, now multiply the decimal by 60 (because there are 60 minutes in an hour, get it??)and you get 40.226358, to the nearest minute its 40 so all together 197 degrees, 40 minutes. is ...

Just expand it ... 8x^3 - 6x^4 - 5x^2 + 10x all done! Why are you calling this trigonometry?

The question is not about trigonometry.

The best tool to solve trigonometry and geometry problems is to draw a diagram. Unless you are very capable of drawing images in your mind, it is always a good idea to draw the figure, label it with all the given information and add more information as you go along. This ...

okay so i have this trigonometry problem were i HAVE to use logarithms. Now this is my work but can u help me solve it using logarithms. Find the area of the following triangles:(use logarithms) 1) c=426, A=45degrees 48' 36",and B=61degrees 2' 13"

trigonometry (repost) Mathmate
I want to start by saying thank you . You have no idea how much u have helped me understand logarithms, even better then the books i have (it poorly explains the subject of trigonometry let alone logarithms and antilog). Your last explanation was very clear and i even ...

Reiny, I interpret "inverse" being inverse trigonometric function, since he is doing a trigonometry course. However, I stand to be corrected!

I really need help with this trigonometry question.please any help is appreciated. 1.I have to draw the graph of y=cos x from 0deg to 360deg. 2.Be sure to show a table of vales similar to the this table. colum X l colum :y=sinx 0 l 0.00 pi/10 l 0.31 pi/5 l 0.59 3pi/10 l 0.81 ...
