Question

FIND ALL TRIGONOMETRIC RATIOS IF TAN THETA=-3/4 AND THETA LIES IN SECOND QUADRANT. PLZ. NO SPAMS.
FOR CLASS 11TH

Answer 1

Answer:

Explanation:

you can start this by making a triangle.

tan Ф = -3/4 = perpendicular(height)/base;

there you now, height = 3;

base =4;

By using pythagorus theorem, hypoteneus=5;

sin Ф=3/5 {height/hypotneus}  (2nd quadrant sinФ will be positive)

cos Ф = -4/5 {base/hypoteneus} (2nd quadrant cos Ф will be negative)

cot Ф = -4/3 (opposite of tan Ф)

cosec Ф = 5/3 (opposite of sin Ф)

sec Ф = -5/4 (opposite of cos Ф)

i hope, it may help you..
