Description

Over 200 items for learning the most important trigonometric formulas

Sample

Q: geom: a÷sin A = 2*R (where: A - the angle of the triangle; a - the length of the side opposite A; R - [...]) A: the radius of the circumcircle (about the triangle)

Q: geom: cos 2A = 1 - 2*(sin^2 A) (where: sin^2 A = ([...] - cos 2A)÷2) A: 1

Q: geom: [...] = -2*(sin (A + B)÷2)*(sin (A - B)÷2) A: cos A - cos B

Q: geom: [...] = 2*t÷(1 - t^2) (where: t = tan A÷2) A: tan A

Q: geom: sin(A - B) = (sin A)*[...] - (cos A)*(sin B) A: cos B
