Therefore the reference angle can be calculated as following:
We know that is:
If then
, therefore
is not defined, because the division by 0 is not defined.
Answer:
x = ± 10
Step-by-step explanation:
To solve the equation let y = 0 , that is
0 = 100 - x²( add x² to both sides )
x² = 100 (I take the square root of both sides )
x = ± = ± 10
Then solution is x = - 10, x = 10
