Factor and simplify:cos2(θ)-1cos2(θ)-cos(θ)

Short Answer

Expert verified

on simplifying we get,1-sec(θ)

Step by step solution

01

Given information

We are given an expressioncos2(θ)-1cos2(θ)-cos(θ)

02

Simplify the expression

We get,

cos2(θ)-1cos2(θ)-cos(θ)=(cos(θ)-1)(cos(θ)+1)cos(θ)(cos(θ)-1)=1+cos(θ)cos(θ)=1+sec(θ)

03

Conclusion

On simplifying we get the expression as1+sec(θ)
