Sin Tan Formula

Sin Tan Formula

The fundamental trigonometric ratios used to analyse how a triangle’s angles and sides relate are the Sin Tan Formula (especially of a right-angled triangle). Hipparchus used the principles of trigonometry to establish the relationship between the sides and angles of a right triangle, whereas Pythagoras focused on the relationship between a right triangle’s sides through the Pythagorean theorem. A right-angled triangle’s missing sides or angles can be found using the trigonometry Sin Tan Formula.

Trigonometry Sin Tan Formula must first be understood by students using formulae and examples.

Sin – Tan x formula

Sin Tan Formula: The sides of a right-angled triangle determine the sine and tangent functions. If theta is a right triangle’s angle, then;

Tan Theta = Opposite side to theta / Adjacent side to theta

  • sin Theta = Opposite side to theta / Hypotenuse of the triangle

The Tan Theta is the ratio of the Opposite side to the Adjacent, where (Θ) is one of the acute angles.

  • Tan Θ = Opposite Side/ Adjacent Side
  • sin Θ = Opposite Side/ Hypotenuse

The two most important trigonometric ratios are the Sin Tan Formula, which yields the ratio of the two sides of a right-angled triangle, respectively. Students must be aware that the three sides of a right-angled triangle are called the “legs” and the “hypotenuse,” respectively. Thus, the longest side of a right-angled triangle is still referred to as the “hypotenuse” in trigonometry, while the other two legs are referred to as the “opposite side” and “adjacent side.”

In trigonometry, the term Sin Tan Formula denotes the values of the corresponding trigonometric functions for the specified angle. By determining the necessary side ratio, students can get the Sin Tan Formula values for a given right triangle.

Tan Sin Formula Questions

In everyday life, the Sin Tan formula for trigonometry is used to calculate heights and distances. Many problems in everyday life may be resolved with sin, cos, and tan. Here is an illustration to help students comprehend how sin, cos, and tan are used.

Example 1: A ladder, for instance, rests against a masonry wall at a 50-degree angle to the horizontal. What height of the wall does the ladder reach if it is 10 feet away from the wall?


Assume for the moment that the ladder extends x feet from the wall.

Using the information provided:

Here, we are aware of the neighbouring side (10 feet), and we must identify the other side (which is x ft). Therefore, we employ the tan relationship between the adjacent and opposing sides.

Tan x/10x = 10tan at 50o 50o\sx ≈ 11.9 ft

Here, the calculator is used to compute tan 50o, and the result is rounded up to 1 decimal place. The ladder, therefore, extends to a height of 11.9 feet from the wall.
