sin is a mathematical operator such as √ , ÷ etc.
by itself it is meaningless, it must have an operand behind it, i.e. sinx or sinØ
(that is like saying: evaluate 1/√ - √ )
1/sinØ - sinØ
= (1 - sin^2 Ø)/(sinØ
= cos^2 Ø/sinØ
which is in terms of sines and cosines as requested
(I would have simplified it to
cotØcosØ )
Add and subtract as indicated. Then simplify your answer if possible. Leave answer in terms of sin(θ) and/or cos(θ). (Remember to enter trigonometric powers such as sin2(x) as (sin(x))2.)
