What is Sin Cos tan used for?

In trigonometry, sin cos and tan values are the primary functions we consider while solving trigonometric problems. These trigonometry values are used to measure the angles and sides of a right-angle triangle. Apart from sine, cosine and tangent values, the other three major values are cotangent, secant and cosecant.

What are the 9 trig identities?

Complementary and Supplementary Trigonometric Identities

  • sin (90°- θ) = cos θ
  • cos (90°- θ) = sin θ
  • cosec (90°- θ) = sec θ
  • sec (90°- θ) = cosec θ
  • tan (90°- θ) = cot θ
  • cot (90°- θ) = tan θ

  • Reciprocal: csc(θ) = csc(θ) = 1/sin(θ)
  • Reciprocal: sec(θ) = sec(θ) = 1/cos(θ)
  • Reciprocal: cot(θ) = cot(θ) = 1/tan(θ)
  • Ratio: tan(θ) = tan(θ) = sin(θ)/cos(θ)
  • Ratio: cot(θ) = cot(θ) = cos(θ)/sin(θ)
  • Pythagorean: sin costs = $1.
  • Pythagorean: I tan = get sic.
  • Pythagorean: I cut = crescent rolls.

What is tan used for?

Tangent is a trigonometric ratio comparing two sides of a right triangle. Tangent is usually shortened to tan but is pronounced tangent. This function can be used to determine the length of a side of a triangle when given at least one side of the triangle and one of the acute angles.

What is the purpose of Cos?

Cos function (or cosine function) in a triangle is the ratio of the adjacent side to that of the hypotenuse. The cosine function is one of the three main primary trigonometric functions and it is itself the complement of sine(co+sine).
