Question

Help me solveeee this

Answer 1

Explanation:

The best way to start this problem is to work on the right.

sec(theta) = 1/ cos(theta.

So the right numerator becomes

1/cos(theta) - 1

Put over a common denominator of cos(theta)

1 - cos(theta)

===========

cos(theta)

Now do the same thing with the denominator on the right.

1/cos(theta) + 1

1 + cos(theta)

=================

cos(theta)

Now put the numerator and denominator together.

1- cos(theta)

----------------

cos(theta)

==============

1 + cos(theta)

-----------------

cos(theta)

Invert and multiply the denominator of that four tier fraction.

1 - cos(theta) cos(theta

========== X ==============

cos(theta) 1 + cos(theta)

cos(theta) cancels out.

1 - cos(theta)

=========

1 + cos(theta)

What you have is the left hand side.
