6. The tangent ratio is y x where (x, y) is a coordinate on the terminal side of the angle
in standard position. Use the diagram to justify why the tangent of 45° is always 1.
Then, expand that reasoning to justify why every individual angle measure nas exactly
one value for tangent. Use similar reasoning to justify why every angle has exactly one
value of sine and one value of cosine.

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit
