1. sin 90° = 1 the most common trigonometric sine functions are sin 90 degree plus theta \(\begin{array}{l}\sin (90^{\circ}+\theta )=\cos \theta\end{array} \) sin 90 degree minus theta \(\begin{array}{l}\sin (90^{\circ}-\theta )=\cos \theta\end{array} \) some ...
while the secondary functions of cosecant, secant, and cot are obtained from the primary functions. 0°, 30°, 45°, 60°, 90°, 180°, 270°, and 360° are the most common degrees. You'll learn how to compute the value of sin 90 degrees, as well as other degrees and radian qua...
theta one interesting fact related to sin 180 degrees is sin 180 minus theta is equal to sin theta, where theta is any angle. sin (180° – theta) = sin theta sin (180° –θ) = sin θ hence, there are three points that we can conclude here: 180° – θ will come in iind...
Now, a bit of math. A circle is 360 degrees. We have 12 labels on our clock, so want to place the numbers every 30 degrees (360 / 12). In math-land, a circle begins at 3 o’clock, so noon is actuallyminus 90 degreesfrom that, which is 270 degrees (360 - 90). Let’s add...
