We begin our exploration of the derivative for the sine function by using the formula to make a reasonable guess at its derivative. Let’s do it in the pattern recognition method, after successive differentiation . First, let’s start with the first differentiation : [math] y_1 = \dfrac{d}{d x} (\cos^2 x) [/math] Now, let’s make the substitutions, I guess that you know that; [ma The derivative of sin 3 x is 3sin 2 x cos x.
