Question

Find value of:3sin 30°+4Cos^2 45° -Cot^2 30° ÷ cos^2 30°+sin^2 30°

Answer 1

1/2

Step-by-step explanation:

3sin30= 1/2*3=3/2

4cos^2 45=4(1/√2)^2=4*1/2=2

cot^2 30=√3^2=3

cos^2 30 = √3/2^2=3/4

sin^2 30=1/2^2=1/4

putting the values we will get the ans that is 1/2

Answer 2

Answer:

= 3×1/2 + 4×(1/√2)² - (√3)² divided by   (√3/2)² + (1/2)²

= 3/2 + 4×1/2 - 3  divided by  3/4 + 1/4 = 4/4 = 1

= 3/2 + 4/2 - 3

= 7/2 - 3 =  7 - 6/2

= 1/2 is the answer...
