1. Trig Function

Mathematics
1 answer:
Dima020 [189]1 year ago
4 0

The values of the given trig functions in terms of sinθ and/or cosθ are:

sinθ = <u>tanθ.cosθ</u>

cosθ = <u>sinθ/tanθ</u>

secθ = <u>1/cosθ</u>

cscθ = <u>1/sinθ</u>

tanθ = <u>sinθ/cosθ</u>

cotθ = <u>cosθ/sinθ</u>

<h3>Trigonometric functions </h3>

From the question, we are to determine the values of the given trig functions in terms of sinθ and/or cosθ

  • sinθ

NOTE: tanθ = sinθ / cosθ

∴ sinθ = tanθ.cosθ

  • cosθ

From above, we can write that

cosθ = sinθ/tanθ

  • secθ

Secant is the <u>inverse</u> of cosine

∴ secθ = 1/cosθ

  • cscθ (cosecθ)

Cosecant is the <u>inverse</u> of sine

∴ cscθ = 1/sinθ

  • tanθ

tanθ = sinθ/cosθ

  • cotθ

Cotangent is the <u>inverse</u> of tangent
∴ cotθ = 1/tanθ

But, tanθ = sinθ/cosθ

∴ cotθ = cosθ/sinθ

Hence, the values of the given trig functions in terms of sinθ and/or cosθ are:

sinθ = <u>tanθ.cosθ</u>

cosθ = <u>sinθ/tanθ</u>

secθ = <u>1/cosθ</u>

cscθ = <u>1/sinθ</u>

tanθ = <u>sinθ/cosθ</u>

cotθ = <u>cosθ/sinθ</u>

Example of six ordered pairs with country names alongside their capitals are:

{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.

<h3>What are Ordered Pairs?</h3>
  • Ordered pair can be described as a pair of objects or numbers in a particular order.
  • In an ordered pair, the order of the objects or numbers are very important. For example, (a, b) is not the same as (b, a).

Therefore, example of six ordered pairs with country names alongside their capitals are:

{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.
