cos^(4)(4)/(5)+tan(3)/(5)=cos(27)/(11)

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

The value of tan[ cos^(-1) ((4)/(5)) + tan^(-1) ((2)/(5)) ] will be

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

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

Prove that : cos^(-1).(4)/(5)+ tan ^(-1).(3)/(5) = tan^(-1) .(27)/(11) (ii) Prove that : sin^(-1).(3)/(5)+ tan ^(-1).(3)/(5) = tan^(-1) .(27)/(11)

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

If tan {cos^(-1)((4)/(5))+tan^(-1)((2)/(3))}=(a)/(b) , where a and b are co-prime natural numbers, then:

Prove that cos^(-1)((4)/(5))+tan^(-1)((3)/(5))=tan^(-1)((27)/(11))

show that cos^(-1)""(4)/(5)+cot^(-1)""(5)/(3)=tan ^(-1)""(27)/(11) .

The value of tan (cos ^(-1) (4)/(5)+tan ^(-1) (2)/(3)) is
