Question

prove that
1/sec@-tan@=sec@+tan@​

Answer 1

1/Sec theta - Tan theta = Sec theta + Tan theta

We have,

LHS = 1/Sec theta - Tan theta

=> 1/Sec theta - Tan theta × (Sec theta+Tan theta)/(Sec theta+Tan theta)

=> (Sec theta+Tan theta)/(Sec²thta-Tan²theta)

=> Sec theta + Tan theta = RHS

=> Sec theta + Tan theta = RHSHence,

LHS = RHS.....PROVED.....
