Question

sin^A+cos^A=?
what is the answer plz reply me now
​

Answer 1

Answer:

sina+cosa=√2(1/√2sina+ 1/√2cosa)

Step-by-step explanation:

sina+ cosa=1 sin a+ cos a

=√2(1/√2 sina+ 1/√2 cos a)

= √2(cos π/4 sin a + sin π\4 cos a)

= √2sin(a+π/4)

Answer 2

Answer:

First of all the value of Sin A + Cos A actually depends on the variable 'a' so we can not actually prodict out the exact answer to this question however we may convert this form into some other trigonometric form which can be convenient to represent as well as to calculate..

Here

I have converted this 2 term function into a single compact term using the formula Sin (A + B ) equal to sin a cos b + cos a sin b ..

Hope it will be helpful to you ..
