cos 2x = cos2 x – sin2 x = (cos x – sin x)(cos x + sin x) from the difference of two squares, we get. dx = dx = dx = sin x + cos x + C provided of course that cos x – sin x ( 0. iv) dx looks a very messy animal and we have to take it a step at a time. We notice from the properties of logs and exponentials that. lne2x = 2x. e3lnx = elnx3 = x3

Use implicit differentiation to differentiate the functions. i) cos–1x ii) tan–1 x iii) (x. Solution. i) If y = cos–1x, then cos y = x. If we now differentiate through with respect to x we have, using function of a function rule: = – sin y = = 1. So = – But sin y = = and so = – ii) …

Jun 14, 2011 · Knowing the deriatives of sin(x) and cos(x), one can easily compute the derivatives of the other circular trigonometric functions because they can all be expressed in terms of sine or cosine; the . quotient rule. is then implemented to differentiate this expression. Proofs of the derivatives of sin(x) and cos(x) are given in the proofs section ...
