Question

if tan theta =4, find all trigonometric ratio?​

Answer 1

Step-by-step explanation:

tan theta = 4

p/b = 4/1

By Pythagoras theorem

h² = p²+b²

h² = 4²+1²

h²= 16+1

h²=17

h=√17

p=4

b=1

h√17

sin theta = p/h = 4/√17

cos theta = b/h = 1/√17

cot theta = b/p = 1/4

sec theta = h/b = √17/1

cosec theta = h/p = √17/4
