Question

please say the four quadrants formulas related to trigonometry


no irrelevant answers
if give i will report their answers ​

Answer 1

ASTC formula has been explained clearly in the figure shown below. In the first quadrant (0° to 90°), all trigonometric ratios are positive. ... In the fourth quadrant (270° to 360°), cos and sec are positive and other trigonometric ratios are negative...

Answer 2

Answer:

Heya !!

sin (180°+θ) = -sin θ

cos (180°+θ) = -cos θ

tan (180°+θ) = tan θ

csc (180°+θ) = -csc θ

sec (180°+θ) = -sec θ

csc (180°+θ) = cot θ

please mark me as brain list...

thank you..
