See you need to do first It is given that tan^-(1/1-x+x²) = tan^-[1/1-x(1-x)] We can write like this As x is taken common Now we can write numerator i.e. 1 as (1-x) + x ... Right? So tan^-[(1-x)+x /1-x(1-x)] We know the formula of Tan^x +tan^y= tan^( x+y/1-xy) On applying on it we get the above result as tan^(1-x) +tan^x Ab iske baad to khud hi kr sakti ho n ?? Ab diffentiate khud hi kr lena answer aa jayega pura solve kr dia hain okk thanks
