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

Prove that: sin^(-1)(-(4)/(5))=tan^(-1)(-(4)/(3))=co^(-1)(-(3)/(5))-pi

Prove that sin^(-1)((4)/(5))+tan^(-1)((5)/(12))+cos^(-1)((63)/(65))=(pi)/(2)

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

Prove that sin^(-1)(4/5)+tan^(-1)(5/12)+cos^(-1)(63/65)=pi/2

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

tan [sin ^(-1)((3)/(5))-cos ^(-1)(-(4)/(5))]=

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

2tan^(-1)(-2) is equal to (a)-cos t^(-1)((-3)/(5))(b)-pi+(cos^(-1)3)/(5)(c)-(pi)/(2)+tan^(-1)(-(3)/(4)) (d) -pi cot^(-1)(-(3)/(4))

cos^(-1) tan(-(5pi)/(4))
