Find all solutions of the equation in the interval [0, 2pi). - 4 sinx= -cos²x+1
Write your answer in radians in terms of pi.
If there is more than one solution, separate them with commas.

x = 0 , π

Step-by-step explanation:

Rewrite it by using the identity

Add 4sin x to both the sides.

Take sin x common from the expression in L.H.S.

Here , we can get two more equations to find x.

1)

Divide both the sides by sin x

Substract 4 from both the sides.

2)

Divide both the sides by (sin x + 4)

over interval [0 , 2π).

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
