Compute for the value of {eq}cos (B) {/eq}. The Cosine of an Angle: The cosine of an angle in a right-angled triangle can be defined as the ratio of its adjacent side and the hypotenuse of the given angle. In this problem, we should find the unknown side using the Pythagoras the...
You might be curious how to find the cosine of an angle. Use the formula below to calculate cos. Cosine Formula The cosine formula is: cos(α) =adjacent/hypotenuse=b/c Thus, the cosine of angle α in a righttriangleis equal to the adjacent side’s length divided by the hypotenuse. ...
The cosine of an angle, α, defined with reference to a right triangle is cos(α)=adjacent sidehypotenuse=bh . The cosine of a complex argument, α, is cos(α)=eiα+e−iα2 . Tips To computecos(X*pi)accurately, without usingpias a floating-point approximation of π, you can...

在\rm{Rt}\triangle BCD中,\cos B=\dfrac{BD}{BC}=\dfrac{\sqrt{5}}{5},\because BC=\sqrt{5},\therefore BD=1.由勾股定理得,CD=\sqrt{(\sqrt{5})^2-1^2}=2.在\rm{Rt}\triangle ACD中,\angle A=45\degree ,\therefore AD=CD=2,\therefore AB=AD+BD=2+1=3.反馈...
An angle, in radians (not degrees), in the range 0 to 2π. Returns The cosine of theta (the result is in the range -1.0 to 1.0). Description The cos( ) function returns the trigonometric cosine of an angle. In a right triangle, the cosine of an angle is the result of dividing ...
The VBA Cos Function stands for Cosine and is used to calculate the cosine of an angle in radians. It is a mathematical function that is commonly used in trigonometry and geometry to find the ratio of the adjacent side to the hypotenuse of a right triangle. This function is also used in...
