The correct option is (d) cotФ.
As, cosineФ/sineФ = cotФ.
<h3>What are trigonometric identities?</h3>
Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions.
There are numerous distinctive trigonometric identities that relate a triangle's side length and angle.
The basic trigonometric identities are-
- Sine, (Sin)
- Cosine, (cos)
- Tangent, (tan)
- Secant, (sec)
- Cosecant (cosec)
- Cotangent (cot)
Solution for the given trigonometric function; (cosineФ/sineФ)
Use formula of tanФ
tanФ = sineФ/cosineФ
Also, from basic trigonometric ratios.
tanФ = 1/cotФ
Substitute sineФ/cosineФ to get the result
1/cotФ = sineФ/cosineФ
Further simplify,
cotФ = cosineФ/sineФ
Therefore, the value of cosineФ/sineФ = cotФ
