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
