Question

IF cos A=1/2, find the value of Cos A (Cos A- sec A)​

Answer 1

Answer:

CosA(cosA-secA)=-3/4

Step-by-step explanation:

cosA=1/2

then , cos 60°=1/2

that means , A=60°

CosA(cosA-secA)=cos60°(cos60°-sec60°)

=1/2(1/2-2)

=1/2(1-4/2)

=1/2×(-3/2)

CosA(cosA-secA)=-3/4

Answer 2

Answer:-3/4
