WebUsing the Cast Rule to Identify Quadrants & the Unit Circle: Example 1 Determine what quadrant the angle 155∘ 155 ∘ is in as well as the signs of sine, cosine, and tangent in that... WebMar 29, 2024 · tan−1(1) = 45o or π 4. On the tan graph the point 1 is repeated but at a different angle so you add 180o to 45o since it is positive. You use the 'CAST' diagram: C- cosine is positive so you do 360o - angle ( angle you calculated) A- all are positive. S- sine is positive so you do 180o - angle. T- tan is positive so you do 180o + angle.
