Question

show that tanø + secø - 1/tanø-secø+1 = 1+sinø/cosø​

Answer 1

Step-by-step explanation:

It is a nice question

First we convert all tan and sec in terms of sin and cos

Then we multiply in numerator and denominator by[ (sin§+cos§) +1]

Then by solving at one point we have to convert cos2§ into 1-sin2§

And then again after solving we gat the prove
