Find the value of ( 1+cosA) (1-cosA)

Mandarinka [93]

Answer:

sin^2 A

Step-by-step explanation:

first expand the trigonometry

1(1-cosA)+cosA(1-cosA)

=1-cosA+cosA-cos^2 A

= 1-cos^2 A

from trigonometric identity sin^2 A + cos^2 A= 1

sin^2 A= 1- cos^2 A

=sin^2 A

Your teacher may also just want the answer y - 2 with a 7 remainder

Either way, you set it up like long division and solve as such.
