Let r be a line of unit length from the origin to the point P (x,y), and let θ be the angle r makes with the positive x-axis. The six functions become sin θ =y/r=y, cos θ=x/r=x, tan θ=y/x, cot θ=x/y, sec θ=r/x=1/x, and csc θ=r/y=1/y. As θ ...
11.Each one of the three laws of cosines begins with the square of an unknown side opposite a known angle. 12.Solving either equation for t directly is not advisable because sine and cosine are not one-to-one functions. 13.We have also studied the variance spectral configuration of surface...
EquationThe principle equation for cosine in a right triangle is:cos(θ) = adjacent side / hypotenuseHow to SolveTo solve for the cosine of a given angle:Identify the angle: Decide the angle you want to calculate the cosine. Use the right tool: Use a scientific calculator, trigonometric ...
The angle π2-θ is known as the complement of θ. Equation (4.14) is equivalent to a catchy-sounding rule: The function of an angle is equal to the corresponding cofunction of its complement. Note that cosine and sine are even and odd functions, respectively: (4.15)cos(-θ)=cosθwhil...
