Adjacent versus Opposite Angles in Right Triangles (Trigonometry)
α α is an acute angle of right triangle ABC A B C. Side BC B C (or a a, which is name given to it using other notation) is its opposite cathetus, while AC A C (or b b) is its adjacent cathetus. AB A B (or c c) is a hypothenuse. Considering this, for example sin α = opposite hypothenuse = BC AB = a c sin α = opposite hypothenuse = B C A B = a c.

Trigonometry? Get the "half" of a triangle from hypotenuse and …
y =yc + mx − mxc (1) (1) y = y c + m x − m x c. Similarly, for line AX we can write: y−ya x−xa = −1 m y − y a x − x a = − 1 m (since line AX is perpendicular to line BC). This leads to: y =ya − x m + xa m (2) (2) y = y a − x m + x a m. Now just equate equations (1) and (2) and solve for x x and then use either of these ...
Name of non-hypotenuse side - Mathematics Stack Exchange
Mar 9, 2018 · There is a specific, Greek-derived name (which I have never heard used in English) for the two short sides of a right-angled triangle. It is cathetus. It's much more common to just refer to them as "legs". The Greek-derived term is used in other languages, though. For instance, in Norwegian, my native language, "katet" is ubiquitous.
Algorithm behind Sin Function - Mathematics Stack Exchange
Feb 10, 2022 · When you put that angle into a right triangle you can calculate the sin sin as a ratio of sides. For example, the 45∘ 45 ∘ angle is the angle in an isosceles right triangle with side length 1 1, so sin45∘ = 1/ 2–√ sin 45 ∘ = 1 / 2, the ratio of the opposite side to the hypotenuse. You would get the same answer from a larger triangle ...

Commented May 25, 2016 at 11:16. A general formula is horrendously complicated and unlikely to be helpful. Label the points P0,P1,P2 P 0, P 1, P 2. The idea is that you want P1P2 P 1 P 2 perpendicular to P0P1 P 0 P 1 and P1P22 =L2 P 1 P 2 2 = L 2. You can express the first condition either by finding the gradient of P0P1 = k P 0 P 1 = k say and ...
laplace equation on a triangle - Mathematics Stack Exchange
May 6, 2019 · u(x = 0, y) = 1 − y 2π u (x = 0, y) = 1 − y 2 π. u(x, 2π − x) = 0 u (x, 2 π − x) = 0. where the lengths of the cathetus are 2π 2 π. From the MVP for harmonic functions I know that the center of a circular domain is given by the average of the value of the boundary. This can obviously not be straightforwardly extended to a square ...
Trigonometry inside a trapezium - Mathematics Stack Exchange
1. The easiest way to solve this problem is to create three right triangles: two of the inside the trapezium, and one outside. the two inside will be created by drawing two lines down from and perpendicular to the top 8 cm leg. This will give you two right …
