WebApr 3, 2024 · Trigonometry in the modern sense began with the Greeks. Hipparchus (c. 190–120 bce) was the first to construct a table of values for a trigonometric function.He considered every triangle—planar or spherical—as being inscribed in a circle, so that each side becomes a chord (that is, a straight line that connects two points on a curve or … WebGiven the lengths of all three sides of any triangle, each angle can be calculated using the following equation. Refer to the triangle above, assuming that a, b, and c are known values. Area of a Triangle. There are multiple different equations for calculating the area of a triangle, dependent on what information is known. WebNow we find sin θ, cos θ, and tan θ using the above formulas: sin θ = Opposite/Hypotenuse = 3/5. cos θ = Adjancent/Hypotenuse = 4/5. tan θ = Opposite/Adjacent = 3/4. Trick to remember sin cos tan formulas in trigonometry: Here is a trick to remember the formulas of sin, cos, and tan.
