On your calculator, input the value of either your sine or your cosine. Then press "inv." This should give you the angle associated with that value. The angle associated with sin 0.923 or cos 0.384 is 67.38 degrees. Add 90 to the angle you just calculated, and subtract the sum from 18...

Often when you are asked to calculate the trig function of an angle without a calculator, you will be given a right triangle, and the angle you are asked about is one of the angles in the triangle. To solve these types of problems, you need to remember the acronym SOHCAHTOA. The firs...

0.5 using one of these methods, then you know which works. However, if you get -0.988 then your calculator is set to radian mode. To change to degrees, look for a MODE key. There is often an indicator of units written right up with the numerals to let you know what you're getting...
Does all of the above seem like quite a bit of trouble to go to for drawing a simple graph? I agree; it is. When working with trig functions, especially those having a phase shift, it may be easier *not* to use the graphing calculator. ...
In most cases, the limits of integration will be clear, especially if you’re using a TI-calculator with an Intersection feature (just find the intersections of the two graphs). If you can find the intersection by graphing, skip to Step 3. Step 2: Find the common solutions of these two...

$\begingroup$ I think that your justification is slightly circular :). In an introductory calculus course, $(\sin x,\cos x)$ is probably defined to be the point we reach after traveling $x$ units counterclockwise along the unit circle from $(1,0)$. $\endgroup$ –Mike F Commented...
