Formula of Multiple Angle

In this article we will learn about Multiple Angle



Sin2θ= 2SinθCosθCos2θ= Cos²θ-Sin²θCos2θ= 2Cos²θ-1Cos2θ= 1-2Sin²θ1+Cos2θ= 2Cos²θ1-Cos2θ= 2Sin²θTan²θ= (1-Cos2θ)/(1+Cos2θ)Sin2θ= (2Tanθ)/(1+Tanθ)Cos2θ= (1-Tan²θ)/(1+Tan²θ)Tan2θ= (2Tanθ)/(1-Tan²θ)Sin3θ= 3Sinθ-4Sin³θCos3θ= 4Cos³θ-3CosθTan3θ= (3Tanθ-tan³θ)/(1-3Tan²θ) I hope you have find this article helpful.

Formula of Compound Interest

In this article we will learn about Compound Interest

If, C.A denotes Compound Amount
P=> Principal
n=> Number of Years
R=> Rate
C.I=> Compound Interest

Compound Interest
Compound Interest

Then,

  • C.A=P(1+r/100)^n
  • C.I=C.A-P or, P(1+r/100)^n-P or, P{(1+r/100)^n-1}
  • P=C.A-C.I
  • C.A=P+C.I
  • C.I=C.A-P
