$$sin^2 \theta = 1$$
Find general solution of $\theta$.

I solved for sin $\theta$ = $\pm$1
and got
$\theta = n\pi + (-1)^n \cfrac{\pi}{2}$
or
$\theta = n\pi + (-1)^n \cfrac{3\pi}{2}$

How to find combined solution

sometimes....i doubt you're really in high school.....

vishweshshrimali5 · Answer

Why ?

lgbasallote · Answer

that kind of trigonometry is rarely taught in high school...

lgbasallote · Answer

...or maybe i just don't know what that is...

vishweshshrimali5 · Answer

That is general solution to trigonometric equation

shubhamsrg · Answer

why dont you treat it like this:
1 = sin^2 @
or
cos^2 @ = 0

easier ?

vishweshshrimali5 · Answer

then I have

cos$\theta$ = 2n$\pi$ $\pm$ $\cfrac{\pi}{2}$

shubhamsrg · Answer

you mean @ = that,,
yep//
