Question

cos2(45+0)+cos2(45-0) whole divided by tan(60+0)tan(30-0)=1​

Answer 1

Answer:

Proved!

Step-by-step explanation:

(cos^2(45)+cos^2(45))/(tan(60)tan(30))

= (1/2+1/2)/(tan(60)*tan(90-30))

= 1/(tan 60 * cot 60)

= 1/(tan 60 * 1/tan60)

= 1/1

= 1

LHS = RHS Hence Proved

Have a Great Day!
