Why -2 - - - Updated - - - y = tan inverse (cot x) + cot inverse (tan x) How answer is -2

if y = tan inverse (cot x) + cot inverse (tan x)

I just trying to learn mathematics that's why I am here if anybody can help please help

if y = sin inverse (x square + 2x) find dy/dx

if y = sin5 + log base10 X +2 sec x find dy/dx if y = sin5 + log base10 X +2 sec x find dy/dx Answer dy/dx= cos5 + 1/(log 5)x+ 2 sec x tanxIs it true answer

I don't know because I am very week in mathematics

No this is not my homework I don't know what is the formula to solving the problem

If y=sin5 + log base 10 x + 2 sec x find dy/dx Please solve the problem

Yes it is true kindly slove the problem

1. find the differential coefficient of root 2 sin x + 4x power5 -3/x power 4 2. if y=(3x square +1)(x square + 2x) find dy/dx.

How sin(h)/(cos(h)+1 =0 please descibe

Hi Thanks for your suggestion But what about c=pi/4 where are used c=pi/4 in the answer

How to find the value of f'(x) at cif 1. f(x)=sinx, c=pi/4 2. f(x)=sinx, c=3pi/2 3.2. f(x)=cosx, c=0, pi/2, pi, 3pi/2, 2pi
