Question

solve for 0 < or equal to x<2pie, give answers to the nearest hundredth of a radian if necessary.
Sin x + Cos x = 0

Answer 1

x= (4n-1) pi/4...
Use sinx + cosx = \[\sqrt{2} \sin (\pi/4 + x) \]
For the given interval of 'x' check which values of 'n' give you the desired solution set...

Hope it makes sense :-)

Answer 2

ok :) thankyou
