Question

please give me formulas of trigonometry all ??? for class 10

Answer 1

Hey !!!

-------------
The formulas for trigonometry are :

tan = sin / cos

cot = cos / sin

sin2 + cos2 = 1

1 + tan2 = sec2

1 + cot2 = cosec2

sin × cosec = 1

cos × sec = 1

tan × cot = 1


Then see the attachment !!!

Answer 2

Trigonometric Formulas:



Applying Pythagoras theorem for the given right-angled theorem, we have:

 

(Perpendicular)2+(Base)2=(Hypotenuese)2

⇒(P)2+(B)2=(H)2
