Question

prove the following equation is an identity:
tan(x)+cot(x)=sec(x)*csc(x)

Answer 1

write them all in terms of sin and cos

Answer 2

1willbe the answer
as sin^2+cos^2=1

enjoy honey .. :)

Answer 3

sin/cos + cos/sin =1/cos*1/sin
=> cross multiply and we get ( sin^2+cos^2)/sin*cos =1/sin*cos
=>sin^2+cos^2=1

:)

Answer 4

thanku!
