Question

secQ-cosQ=sinQtanQ

Prove​

Answer 1

here it is answer

replace secQ with 1/cosQ then after solving you'll get (1-cos²Q) /cos Q which is sin²Q/cosQ

hence sinQtanQ

Answer 2

Step-by-step explanation:

secQ = 1/cosQ

secQ - cosQ = 1/cosQ - cosQ

=. 1-cos²Q /cosQ

=. sin²Q/cosQ

=. sinQ (sinQ/cosQ)

=. sinQ.tanQ
