How do you find the values of #theta# given #tantheta=1#?
You then do inverse tan to find what it is in degrees or radians:
On the tan graph the point 1 is repeated but at a different angle so you add
C- cosine is positive so you do
A- all are positive
S- sine is positive so you do
T- tan is positive so you do
180+45= 225 degrees or
