sin²A + cos²A = 1
This is a trigonometric identity.
The method for this question:-
tanA = 1/√3
we know,
tan30° = 1/√3
so, A = 30°
sin²30° + cos²30°
=> (1/2)²+(√3/2)²
=>1/4+3/4
=>1+3/4
=>4/4
=>1
Cheers!
Abhirabhi:
U guys didnt answer to the question..we can use this identity to check if our answer is correct..(anyways ) but inorfer to solve this u need to find the value of A . Substitude in sin and cos and find its respective vaues and should find the answer. Anyway u will get one. But if the question was for four marks what will u do
listen, if th question was about ven for 1 marks i would still have answered
the* for* even* *mark
and secondly, yes the thing you stated can also be one solution, but i wrote the first thing that appeared ib my mind
