Question

Find an exact simplified solution to the equation on the interval 0 < x < 1.
1 = 6cos(x + 1) − 2

Answer 1

just try to solve for cos
what do you get ?

cos(x+1) = ??

Answer 2

i got basically this 1/2= cos(x+1)
so cos = pi/3 or 5pi/3
but it is not in the set parameter

Answer 3

very good

this is because you forgot to subtract 1 :)

x+1 = pi/3

x = pi/3 - 1

Answer 4

5pi/3 - 1 is outside parameters of course

Answer 5

oh ok thank you so much

Answer 6

yw
just remember when you get the angle you still have to set it equal to whatever is in parenthesis
