Question

If cos A=√3, then sin A is__​

Answer 1

Answer:

cosA=√3;

sinA=√(1-cos^2(A))

=√(1-3)

=√2i (this is an imaginary no.)

Answer 2

please mark as BRAINLIEST answer

Answer:

sin²a+cos²a=1

sin²a+(1/root under3)²=1

sin²a=1-1/3=2/3=root under2/root under3

since tan a= sin a/cos a

root under 2/ root under 3÷1/ rootunder 3

rootunder2/rootunder3 ×rootunder3/1

Ans= rootunder 2
