To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions.
Sin 2x formula is the double angle formula of sine function and sin 2x = 2 sin x cos x is the most frequently used formula. But sin 2x identity in terms of tan is sin 2x = 2tan(x) /(1 + tan 2 (x)). What is Sin 2A in Terms of Cos?
is y = sin(x) a one-to-one function? plot sn(x, 0.9), sn(x, 0.8), sn(x, 0.7), sn(x, 0.6), sn(x, 0.5), sn(x, 0.4), sn(x, 0.3), sn(x, 0.2), sn(x, 0.1), sin(x) from x = -10 to 10 sin(x+i y)
The two formulas of sin squared x are i) sin^2x = 1-cos^2x and ii) sin^2x =(1 - cos 2x)/2.
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 $\sin^2 x$:
