see my worksheet below.



i used x instead of theta.
no change in the formulas except a change of variable name.

step 1 shows the original equation.

step 2 changes cot(x) to equivalent form of 1/tan(x). and changes sec(x) to equivalent form of 1/co(x).

step 3 converts 1/(1/tan(x)) to equivalent form of tan(x) and converts 1/(1/cos(x)) to equivalent form of cos(x).

note that 1/tan(x) * 1/cos(x) is equivalent to 1 / (tan(x)*cos(x)) and that 1 / (1 / (tan(x)*cos(x))) = tan(x) * cos(x).

step 4 converts tan(x) to equivalent form of sin(x) / cos(x).

step 5 cancels cos(x) in numberator and denominator, leaving sin(x) = sin(x) which is true.

the original equation is confirmed to be true.

Poorly worded post.... The objective is to show that the expression on the left is identical to the expression on the right.
