The Attempt at a Solution
How do you solve this for x?
getty102 said:Well I came up with;
(1+2cos(2x))sinx=3sinx
but that didn't work either
To set functions equal to each other to cancel, you first need to identify the two functions that you want to set equal. Then, you need to solve for the variable in each function. Finally, you can set the two equations equal to each other and solve for the variable, which will result in the functions canceling each other out.
Setting functions equal to each other to cancel is a useful technique in algebra, especially when solving systems of equations. It allows you to eliminate one variable and solve for the other, making the problem simpler and easier to solve.
Yes, there are some limitations to this technique. It only works when the two functions have the same variable and the same coefficient. If the functions have different variables or coefficients, you cannot set them equal to each other to cancel.
Yes, you can set multiple functions equal to each other to cancel. However, it will require more steps and may become more complex. It is recommended to use this technique with only two functions at a time.
No, there are other methods to solve systems of equations, such as substitution, elimination, and graphing. However, setting functions equal to each other to cancel is a quick and efficient method, especially when the equations are already in a simplified form.
