height of the ride at the peak of the arc? Use Trigonometric Functions coterminal angle: –200° + 360° = 160° reference angle: 180° – 160° = 20° Sine function = 20° and r = 89 89 sin 20° = y Multiply each side by 89. 30.4 ≈ y Use a calculator to solve ...
Secondly Madhava's table concentrates on values of sin, which are useful but limited (more modern tables will also have values of cos, tan and cot and possibly the other ratios as well), while the holistic approach of P322(CR) gives you the entire triangle, and you can choose which ...
Find the exact value of sin(−19π4). Sine Function:In trigonometry, the sine function is defined as the ratio of the opposite side's length to the hypotenuse's length in a right-angled triangle. The sine function is used to calculate a right triangle's unknown angle or side. ...
