Inverse cosine function. The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y. Example. arccos 1 = cos-1 1 = 0 rad = 0° See: Arccos function. Cosine table

Provade  Hej jag ska lösa uppgiften sin x = cos x grafiskt. Men jag behöver hjälp, vet inte hur jag ska. If sin2x=1, then find value of det[[0,cos x,-sin xsin x,0,cos xcos x,sin x,0]]^(2) Grafen till y = sin x + cos x. Även om man adderar en sinusfunktion med en cosinusfunktion så blir det Vi visar att D \sin x = \cos x. Vi arbetar med definitionen av derivatafunktionen, f'(x)=\lim_{h \to 0}\frac{f(x+h)-f(x)}{h}. Derivatan av D\sin x = \lim_{h \to 0}  Answer to 9. let a = [ SIN X COS X -COS X SIN X 1.
