<p>do I need to memorize all the trig values for every number?</p>
<p>Of course not!`</p>
<p>If you have worked with them enough, it’s easy to remember them. Usually they’re your regular 30-60-90, 45-45-90, or 3-4-5 triangles. Of course they’re not gonna ask you for the sin 57 degrees without a calculator.</p>
<p>Or you can always draw a quick sketch of a triangle with those measurements and do the sides, you can figure out the trig values from there.</p>
<p>how are you studying for this exam? just wondering because im taking it too</p>
<p>Yes I agree, you need to know those for the angles 45, 30, 60. that’s all.</p>
