It is indeed true that \sin^{2}(x)=1-\cos^{2}(x) and that \sin^{2}(x)=\frac{1-\cos(2x)}{2}. Notice that cos 2 ( x ) : = ( cos ( x ) ) 2 is not the same thing as cos ( 2 x ) . It is indeed true that sin 2 ( x ) = 1 − cos 2 ( x ) and that sin 2 ( x ) = 2 1 − c o s ( 2 x ) .

We will start from the left side and prove the right side. ==> we know that: 2011-02-26 · So tan(2x) / [sin(2x) + cos(2x)] can become as big as one likes and is as a result unbounded. By the way, a simpler way to see this isn't an identity is to alternative x = pi. The left side turns into 0/(zero + 1) = 0, however the correct facet becomes 0 - 1 - 1 = -2. Lord bless you today!

Differentiate sin(2x)/x^2 w.r.t. x. Quotient Rule:d(u/v)/dx = (vu' - uv')/(v2)u = sin(2x) => u' = 2cos(2x)v = x2 => v' = 2x=> (2x2cos(2x) - 2xsin(2x))/(x4)Product
