evablogger [386]

Answer:

15 = 9 + 5j

Prove that:cos^2(45+A)+cos (45-A)=1​
krek1111 [17]

Step-by-step explanation:

\boxed{cos^2x=\frac{1-cos2x}{2}}\\cos^2(45+A)+cos^2(45-A)=\frac{1-cos2(45+A)}{2}+\frac{1-cos2(45-A}{2}\\=\frac{1 - cos(90 +2A) }{2}   +  \frac{1 - cos(90  - 2A) }{2}   \\  =   \frac{2- ( - sin 2A)  - sin2A}{2} \\ =  \frac{2 + sin2A -sin2A }{2}  \\  =  \frac{2}{2}  \\  = 1
