Question

cot²π/4+sec²π/4-4cosπ/3​

Answer 1

Answer:

1

Step-by-step explanation:

first of all,

π/4= 45°.

π/3=60°.

so according to question,

cot^2(45°)+sec^2(45)-4cos (60).

(1)+(√2)^2- 4(1/2).

1+2-2.

Answer 2

Step-by-step explanation:

we know that:-

cotπ/4 = 1

secπ/4 = √2

cosπ/3 = 1/2

hence:-

cot²π/4 + sec²π/4 - cosπ/3 = 1² + (√2)² - 4× 1/2

= 1 + 2 -2 = 1

hope it's help you...... ☺️☺️

have a sweet night dear ❤️❤️ and thanks for asking
