Question

pls solve this trigonometric question!!​

Answer 1

Step-by-step explanation:

cos(60°) => 1/2

sin(60°) => √3/2

tan(60°) =>√3

cot(45°) => 1

sec(30°) =>1/cos(30°) => 1/(√3/2) =>2/√3

(cos(60°)^4+sin(30°)^4) => ((1/2)^4 +(√3/2)^4) => (1/16+9/16)=>5/8.

tan(60°)^2 + cot(45°)^2 => (√3×√3) +1 =>4.

3 sec(30°)^2 =>3(4/3) =>4.

The answer for question 2 is 5/8. Hope it helps you.
