Question

verify :cot^2 30°(sec 30° - 1)=sec^2 30°[1-sin30/1+sec30°]​

Answer 1

Answer:

Step-by-step explanation:

cot² 30° (sec 30°-1)=sec² 30°[1-sin 30°/1+sec 30°],

Substitute the given values from the table :

(√3)² (2/√3-1)=(2/√3)²[1-1/2 ÷ 1+2/√3],

3*2-√3/√3=4/3*[1/2 ÷ √3+2/√3],

6-√3/√3=4/3[1/2*√3/√3+2],

6-1=4/3[√3/2*(√3+2)],

5=4/3*√3/2√3+4,

5=√3/3*2√3,

5=√3/6√3,

5 is not equal to 1/6,
