Question

if sin x +cos y , then x +y is ?

Answer 1

its a unit circle problem having yo do with pi/2

Answer 2

Oh. Is the angle pi/2?

Answer 3

its asking if always equal to pi/2
always equal to pi
sometimes equal to pi/2
or never equal to pi/2

Answer 4

Does it not say what sinx + cos y equals?

Answer 5

Are x and y part of the same triangle?

Answer 6

ur right equals my bad

Answer 7

I can't find an example that when sinx = cosy that x + y doesn't equal pi/2.

Answer 8

so it always equals it

Answer 9

As far as I can tell.

Answer 10

Can you find a counter example?

Answer 11

no ive been looking

Answer 12

I'm thinking this --> sometimes equal to pi/2

Let x = y = (5π)/4

sin (5π)/4 = cos (5π)/4 = -√2 / 2

but (5π)/4 + (5π)/4 　≠ π/2
