You can put this solution on YOUR website! 1) On the TI-86 calculator, you would enter the number of degrees in the keypad, then push the SIN key for the sine of that angle, or the COS key for the cosine of the angle, or the TAN key for the tangent of the angle.... Using the identity that the sin of an angle plus a right angle (90 degrees or pi/2 radians) is equal to the cosine of the angle, you can write both in terms of each other. Therefore it is a matter of preference.

The graphs of sin, cos and tan: The following graphs show the value of sinÃ¸, cosÃ¸ and tanÃ¸ against Ã¸ (Ã¸ represents an angle). From the sin graph we can see that sinÃ¸ = 0 when Ã¸ = 0 degrees, 180 degrees and 360 degrees.... 22/03/2010Â Â· What I need to know is when to use Sin instead of Cos for the x-axis or Cos for the y-axis when using Newton's laws and solving for forces. For example: A car of mass m is on an icy driveway inclined at an angle (theta).

## How To Know Whether To Use Cos Sin Or Tan

### What matters is that Professor Parent's goal was to derive an expression for sin(1) whose computation requires only the four basic arithmetic operations and square roots (see the expressions he has provided for sin(45), sin(30), sin(60), sin(75), sin(15), sin(36), sin(18), sin(3), sin(6), and sin(72)). However, I maintain that the computation of the expression he has provided for sin(1
