Fatima wants to find the value of sine theta, given Cotangent theta = four-sevenths. Which identity would be best for Fatima to use?
cosine theta = StartFraction 1 Over secant theta EndFraction
sine squared theta + cosine squared theta = 1
Cosecant theta = StartFraction r Over y EndFraction
1 + cotangent squared theta = cosecant squared theta

Respuesta :

Answer: D, or 1+cotangent squared theta= cosecant squared theta

Step-by-step explanation: Took the test it is right

The  identity that would be best for Fatima to use is:

  • cosine theta = StartFraction 1 Over secant theta EndFraction

What is cos theta over sin theta?

The term cos theta over sin theta is known to be Cotangent. This is because it is seen and defined as x over y is cosine theta over sine theta.

The three types of trigonometric identities are;

  • sin2θ + cos2θ = 1.
  • 1 + tan2θ = sec2θ
  • 1 + cot2θ = cosec2θ

Note that Trigonometric identities are known or regarded as a kind of equations that is made up of  trigonometric functions that are said to holds true for all the value of the variables that is used. In the above, the formula given will help Fatima to find the value of sine theta.
