Since must be in the range of arcsin x (i.e., [ / 2, / 2] ), we know cos must be positive. The derivative of arccos x is given by -1/ (1-x 2) where -1 < x < 1. It is one of the important inverse trigonometric functions. . The function cosh is even, so formally speaking it does not have an inverse, for basically the same reason that the function g ( t) = t 2 does not have an inverse. We know that sin 2 x + cos 2 x = 1, by simplifying this formula to get our answer, we simplified it till the 6th line of the below figure. dy dx = 1 1 +cot2y using trig identity: 1 +cot2 = csc2. Solved example of derivatives of inverse trigonometric functions. Inverse cosine is the inverse function of the cosine function. The usual definition of cosh 1 x is that it is the non-negative number whose cosh is x. Since we know that the derivative of cos inverse x is -1/(1 - x 2), where -1 < x < 1, we will prove it using the definition of limits, that is, the first principle of differentiation. Differentiation of cos inverse x or c o s 1 x : If x (-1, 1) , then the differentiation of c o s 1 x with respect to x is 1 1 x 2. i.e. Learning math takes practice, lots of practice. Voiceover: In the last video, we showed or we proved to ourselves that the derivative of the inverse sine of x is equal to 1 over the square root of 1 minus x squared. Now using the formula as written in line 2 of the below figure we can write our expression dx/dy = cos y, if we reciprocal this term we get dy/dx = 1/cos y this. In other words, the rate of change of cos x at a particular angle is given by -sin x. This video is only available for Teachoo black users.
