expand (cot(θ)+1)(sec(θ)-1)

expand

(cot (θ) + 1) (sec (θ) - 1)

cot (θ) sec (θ) - cot (θ) + sec (θ) - 1

Solution steps

(cot (θ) + 1) (sec (θ) - 1)

Apply FOIL method

(cot (θ) + 1) (sec (θ) - 1) : cot (θ) sec (θ) - cot (θ) + sec (θ) - 1

= cot (θ) sec (θ) - cot (θ) + sec (θ) - 1

2 (8 - 3)

\frac{5 ( 2 cos ( 2 ) x + 4 cos ( 2 x ) + 3 )}{4}

\frac{( x + 3 ) ^{2}}{( x - 5 )}

(1 - i + t)^{2}
