Why Is Sin The Y Value? [Solved]
The sine function relates a real number t to the y-coordinate of the point where the corresponding angle intercepts the unit circle. More precisely, the sine of an angle t equals the y-value of the endpoint on the unit circle of an arc of length t . In Figure 2, the sine is equal to y .
Why does cos(t)=x and sin(t)=y?
Why do you sometimes see “x= cos(t),
The value of the expression 1-sin^2y/(1+cosy)+(1+cosy)/siny-siny/(1-cosy) is equal to
