1-sin 60 degree/ cos 60 degree = tan 60 degree - 1/tan 60 degree +1​

Answer 1

Step-by-step explanation:

Here is your answer.

WE KNOW THAT-

SIN 60°= √3/2

COS 60°= 1/2

TAN 60°= ✓3

PUTTING THE VALUES IN THE GIVEN EQUATION WE GET,

» 1-✓3/2 / 1/2 = ✓3-1 / ✓3+1

» 2-✓3/2 × 2/1 = ✓3-1 / ✓3+1

» 2-✓3 = ✓3-1 / ✓3+1 × ✓3-1 / ✓3-1

» 2-✓3 = (✓3-1)² / (✓3)² - (1)²

» 2-✓3 = 3+1-2✓3 / 3-1

» 2-✓3 = 4-2✓3 / 2

» 2-✓3 = 2-✓3

LHS = RHS
