The law of sines, or the sine rule, tells us that the ratios between a triangle's sides and the sines of their corresponding angles are the same. For... Learn more about this topic: Using Sine to Find the Area of a Triangle
This video show you how to use the Cosine rule The area of a triangle The area of any triangle is ½ absinC (using the above notation). This formula is useful if you don't know the height of a triangle (since you need to know the height for ½ base × height)....
Sine law relates the length of sides to the sine of angles of a triangle. Explore the concept using calculator, solved examples and FREE worksheets with Cuemath.
Right triangle used to define trigonometric functions. (4.12)sinθ≡oppositehypotenuseandcosθ≡adjacenthypotenuse. Later we will also deal with the tangent: (4.13)tanθ≡oppositeadjacent=sinθcosθ. A popular mnemonic for remembering which ratios go with which trigonometric functions is “SOHCAHTOA,...

Trigonometric functions are used to find ratios between the sides of a right triangle. For example, given the following right triangle: Right triangle If using ∠y, the sin y = BC This is because the ratio for sin is opposite the angle over the hypotenuse of the triangle.View...
Sine function is a trigonometric function that is equal to the ratio of perpendicular and hypotenuse of a right triangle. Learn sine function definition, formula, properties, values for different angles, at BYJU'S.
