Is there any solution for the equation sin x = 2? The answer is yes if you accept complex numbers. However, the reader should know a bit of complex numbers and trigonometry. Let us start with Euler’s Identity: e ix = cos x + i sin x (1) Replace x by –x, and note that sin(-x) = - sin x, we get :

sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x As many people have pointed out by now, $\sin^2 x$ is simply a "nickname" for $(\sin x)^2$. Therefore, $\sin^2\ 30 = (\sin 30)^2 = (1/2)^2 = 1/4$. As it happens, though, there is another useful thing we can say about $\sin^2 x$: $$\sin^2 x = (\sin x)^2 = \frac12 (1 - \cos (2 x)).$$ We can see this using the double-angle formula for cosines How to integrate sin^2 x using the addition formula for cos(2x) and a trigonometric identity.

The trick is to rewrite the $\cos^2(x)$ in the second step as $1-\sin^2(x)$. Then we get Click here👆to get an answer to your question ️ If tan x = 3/4, pi < x < 3pi/2 .
