Math Trigonometry Trigonometric Functions: Soh-Cah-Toa: shows how to relate the sides of a right triangle using the hypotenuse, adjacent and or opposite sides

WHAT ARE THE SIX FUNDAMENTAL TRIGONOMETRIC RATIOS? Trigonometric formulas are the six basic trigonometric ratios which establish the ratios of the lengths of the sides with each other in a right angled triangle. the three fundamental trigonometric ratios as sin, cos and tan, which their reciprocal trigonometric ratios cosec, sec and cotan are derived trigonometric ratios.

A pixelized christmas tree made via Microsoft Excel vba with the formula : Sin(Cos((y / 2) ^ 2 - (x - 50) ^ 2)) * y / 2 > Cos(Sin((x - 50) ^ 2 - (y / 2) ^ 2)) * Abs(x - 50) Then Condition = TRUE (x=col nr, y=row nr; if condition = TRUE, cell is colored in green)

Complex numbers in polar coordinates: r^2 = a^2 + b^2; (r is the magnitude, modulus or absolute value of the complex number); (theta is the argument); tan(theta) = b/a; theta = arctan(b/a); cos(theta) = a/r, sin(theta) = b/r so a=rcos(theta) and b=rsin(theta); complex number written as: z=real part + imaginary part; z = rcos(theta) + rsin(theta)i = r(cos(theta) + isin(theta)) = e^i(phi) - Euler's formula

Addition and Subtraction Formulas for Sine and Cosine: In a right triangle with legs a and b and hypotenuse c, and angle alpha opposite side a, the trigonometric functions sine and cosine are defined as sin(alpha) = a/c, cos(alpha) = b/c
