cos[tan^(-1)((3)/(4))]

Prove that cos^(-1)((4)/(5))=tan^(-1)((3)/(4))

1.What is the value of tan[(1)/(2)cos^(-1)((3)/(5))]+tan[(1)/(2)cos^(-1)((4)/(5))] ?

Solve : cos(tan^(-1)x)=sin(cot^(-1)""(3)/(4))

Write the value of cos^(-1)(tan((3pi)/4)) .

tan [cos ^ (- 1) ((3) / (4)) + sin ^ (- 1) ((3) / (4)) - sec ^ (- 1) 3]

Find the principal value of each of the following: (i) cos^(-1)(sin((4pi)/3)) (ii) cos^(-1)(tan((3pi)/4))

tan(cos^(-1)((3)/(5))+tan^(-1)((1)/(4)))

tan [cos^(-1)((4)/(5)) +tan ^(-1)((2)/(3))]=....

Prove that. tan^(-1)((1)/(4)) +tan^(-1)((2)/(9)) =(1)/(2) cos^(-1) ((3)/(5)) .

Prove that: tan^(-1)((1)/(4))+tan^(-1)((2)/(9))=(1)/(2)cos^(-1)((3)/(5))
