 Sep14 revised Finding a side given 2 angles and a side (and rationalizing a denominator afterwards) added 173 characters in body Sep14 comment Finding a side given 2 angles and a side (and rationalizing a denominator afterwards) Thank you guys for that part! Now I having trouble rationalizing the denominator.. any help? (I editted the question to show this).

Same for you, @Hans. Sep13 accepted Finding all Trigonometric Solutions of an Equation within a Given Interval Sep13 comment Finding all Trigonometric Solutions of an Equation within a Given Interval Aha, wait a moment! Following @Arturo's comment, I got $\sin x = -1/2$, which is either $7\pi/6$ or $11\pi/6$, right? Sep13 comment Finding all Trigonometric Solutions of an Equation within a Given Interval I see that theres one more solution just beyond $\pi$ when I graphed the 2 functions, but I still can't reason out what it is. I tried following @Arturo's previous comment, but to no avail. Sep13 comment Finding all Trigonometric Solutions of an Equation within a Given Interval Is it not just $0$ and $\pi$? Sep13 comment Finding all Trigonometric Solutions of an Equation within a Given Interval I eventually simplified to the point that I got $\sin x = 0$, thus making the solutions $0$ and $\pi$. Is this correct? Sep13 comment Finding all Trigonometric Solutions of an Equation within a Given Interval I'm sorry, @Srivatsan, I'm confused. Could you re-word that? Sep13 comment Finding all Trigonometric Solutions of an Equation within a Given Interval So If I substitute, I get $1 - 2sin^2x - sinx = 1$, which is $-2sin^2x - sinx = 0$. Is there a way to simplify this further?

Thank you both Brian M. Scott and Austin Mohr for your help. It is greatly appreciated. Sep10 accepted Given that $s$ is an even function and $t$ is an odd function, is $s(t(x))$ even or odd?

I would believe even. Substituting $-t(x)$ in your previous statement for $u$, for the sake of argument, $s(-u)$ = $s(u)$, since $s$ is even. Substituting back in, $s(t(-x)) = (s(t(x))$, making it even, correct? Sep10 asked Given that $s$ is an even function and $t$ is an odd function, is $s(t(x))$ even or odd?
