Find all solutions to the equation cosxcos(3x)+sinxsin(3x)=0 on the interval [0,2pi]​

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

range is infinite on both x and y axis positive and negative

35-60 students are taking math.

if you was gonna solve for a, a is a   < -12
