Math Problem Statement
tan(x)-cot(x)=2
Solution
To solve the equation , we can follow these steps:
Step 1: Express in terms of
We know that: So, the equation becomes:
Step 2: Multiply the entire equation by to eliminate the fraction
Step 3: Rearrange the equation to form a quadratic equation
Step 4: Solve the quadratic equation using the quadratic formula
The quadratic formula is given by: Here, , , and .
Substitute these values into the formula:
Step 5: Simplify under the square root
Step 6: Solve for the two possible values of
Step 7: Find the corresponding angles
We now have two equations: These values for do not correspond to standard angles, so can be found using the arctangent (inverse tangent) function: These solutions will give the principal values of , but since the tangent function is periodic with period , the general solutions will be: where is any integer.
