Differentiating cos squared x
WebAt a point x = a x = a, the derivative is defined to be f ′(a) = lim h→0 f(a+h)−f(h) h f ′ ( a) = lim h → 0 f ( a + h) − f ( h) h. This limit is not guaranteed to exist, but if it does, f (x) f ( x) is … WebFirst, you should know the derivatives for the basic trigonometric functions: \dfrac {d} {dx}\sin (x)=\cos (x) dxd sin(x) = cos(x) \dfrac {d} {dx}\cos (x)=-\sin (x) dxd cos(x) = −sin(x) …
