Question

त्रिकोणमिति फलन के अनुपात का सूत्र​

Answer 1

Answer:

please mark me as brainliest

Step-by-step explanation:

त्रिकोणमिति के मौलिक सूत्र (important formulas of trigonometry)

sin2α + cos2α = 1.

tan α . cot tan α = 1.

tan α = sin α / cos α = 1 / cot tan α

cot tan α = cos α / sin α = 1 / tan α

1 + tan2a = 1 / cos2a = sec2a.

1 + cot tan2a = 1 / sin2a = cos sec2a.

Answer 2

sinx = p/h

sinx = p/hcosx = b/h

sinx = p/hcosx = b/htan x = p/b

sinx = p/hcosx = b/htan x = p/bcotx = b/p

sinx = p/hcosx = b/htan x = p/bcotx = b/psecx = h/b

sinx = p/hcosx = b/htan x = p/bcotx = b/psecx = h/bsinx = h/p
