more trig.... how fun!!!!
if you can't help me with my first question hopw you can help me with this one. sec(-x)/csc(-x)=tan(x) thanx to anyone who can help From the definition of the sec and csc functions, and the tan function, sec(-x)/csc(-x) = sin(-x)/cos(-x) = tan(-x) However, tan (x) does not ...

Use the Quadratic Formula to solve the equation in the interval [0,2pi). Then use a graphing utility to approximate the angle x. (1) 5/(tanx+secx) (2) 4cos^2x-4cosx-1=0 Thank you.

1) is not an equation 2) cosx= (4+-sqrt(16-4*(4)(-1))/8= you do it check my thinking.

the instructions probably say: evaluate the exact value of .... that means, you do not use a calculator. (That does not mean we cannot use one to check the answer we find) the trick for all of these is to split the given angle into two or more parts whose trig values we know ...

I figured it out before I got your answer, and I used the trig identity sin(t-u)=sin(t)cos(u)-cos(t)sin(u). I ended up having to use four or five more trig substitutions before finally getting to the answer you have there. Your substitution is much easier to compute. Too bad I...

Your details for each type of writing are fine. The only thing I would add is to "address the opposing view(s)" in persuasive writing. Prompt suggestions: Fictional narrative -- 1) Three siblings think it'll be great fun to play in the deep snow outside, but they find that it'...

Good comment, Reiny. I generally eschew working on homework dumps, but I have always enjoyed the many ways trig functions can be combined. Some of those tan-sec identities in the previous batch stumped me, though. Today's problems were pretty straightforward. Still, Kewal, it ...

graphing trig functions
You can pick as many x points as you want. The more you plot, the easier it is to plot a smopoth and accurate curve. For the y values that go with each x, you need a calculator, a special slide rule or a table of trig functions. Hardly anyone uses tables or slide rules anymore.

first of all, to make things easier to type, let's say h = delta x so your question becomes lim [ sin(π/6 + h) - sin π/6 ]/h , as h ---> 0 This looks like you want the derivative of sin x, when x = π/6 if f(x) = sinx f'(x) = cosx f'(π/6) = cos π/6...
