cos (3pi x/3) = 0.5

The number of answers depends on the range of angles. I will solve this question using the range 0<x<2 pi. Draw a unit circle, you will see that the quadrants where cosine gives a positive value are the first and the fourth quadrants.

The Angles whose cosines give + 0.5 are: pi / 3 and 5pi / 3. (Note that 7 pi/3 and 11 pi/3 are also possible solutions but they lie out of the range 0<x<2pi.)

3pi x/3 = pi/3 OR 3pi x/3 = 5pi/3

Here you can solve the equations to give x = 1/3; 5/3

Q: How do you find the general solution for cos of 3x- pi over 3 equals 0.5?

x= -15, would you like me to explain, comment

No. The solution to the equation is 1/3. To solve: 27x - 5 = 4 (add 5 to each side to separate knownsa from inkowns) 27x = 9 (now divide both sides by 27 to find the value of x) x = 1/3 (solution)

You multiply both sides by 5 to clear the fraction and get the answer x equals 15.

Find the derivative of Y and then divide that by the derivative of A

It's an algebraic equation in one variable. [ x=6 ] is its solution.

No. The solution to the equation is 1/3. To solve: 27x - 5 = 4 (add 5 to each side to separate knownsa from inkowns) 27x = 9 (now divide both sides by 27 to find the value of x) x = 1/3 (solution)

x/4 - 4 = x/4 4x/4 - 4 x 4 = x x - 16 = x 0 = 16 There is no solution to the equation.

2 x 22/7 = 44/7 or 6 2/7

You multiply both sides by 5 to clear the fraction and get the answer x equals 15.
