Question

pls solve this....


IF YOU ARE NOT SURE ABOUT YOUR ANSWER THEN DON'T GAVE PLS OTHERWISE I WILL REPORT I'D AND ANSWER BOTH

Answer 1

here is your answer dear

Answer 2

Sin@ + 2 Cos@ = √3

Sin^2 @ + 4 Cos^2 @ + 4 Sin@. Cos@. = 3

1 + 4 Sin@ . Cos@ = 3 Sin^2 @

Cos^2 @ + 4 [email protected]@ = 2 Sin^2 @

devided by Sin^2 @ :

Cot^2 @ + 4 Cot @ = 2

Cot ^2 @ + 4 Cot @ - 2 = 0

then you got....

value of Cot @ = ??

after that you found the value of Tan @ = 1/ Cot @

then you solve your equation :

4Tan^2 @ + Cot^2 @ = ??
