This cos 2 theta calculator will teach you all there is about the double angle formula for the cosine function.
For example, {eq}\sin ^{2} \theta + \cos^{2} \theta = 1, 1+ \tan^2 \theta = sec^{2} \theta, {/eq} etc. Here, {eq}\sin {/eq}, {eq}\cos {/eq}, {eq}\sec {/eq}, and {eq}\tan {/eq} are the trigonometric ratios....
Calculate {eq}\frac{d^6}{d \theta ^6} (\cos 3 \theta) {/eq}. Sixth Derivative of Cosine Function: In the computation of the sixth order derivative of a trigonometric function, we need to know about the common derivatives (with respect to the variable {eq}\theta {/eq}) of the si...
