Question

1.If √3tanA= 3sinA, find the value of sin A.

2.If cotA +(1/cotA) = 2, find the value of [cot²A +(1/cot2²A)].

3.If √3tan2A-3=0, find the value of A.

4.If tan(3x+30°) = 1 then find x.​

Answer 1

[cot²a +(1/cot2²a)].[cot²A +(1/cot2²A)]. cotA +(1/cotA) = 2,1.If √3tanA= 3sinA cotA +(1/cotA) = 2,1.If √3tanA= 3sinA1.If √3tanA= 3sinA cotA +(1/cotA) = 2, cotA +(1/cotA) = 2,1.If √3tanA= 3sinA cotA +(1/cotA) = 2, cotA +(1/cotA) = 2,[cot²A +(1/cot2²A)].
