Because it is understood that sine and cosine are functions, we do not always need to write them with parentheses: sint is the same as sin(t) and cost is the same as cos(t). Likewise, cos2t is a commonly used shorthand notation for (cos(t))2.

WebWe're trying to figure out an angle but we don't know 3 of the sides. The Law of Cosine just doesn't seem, at least in an obvious way, that it's going to help me. I could also try to find this angle. Once again, we don't know all 3 sides to be able to solve for the angle. So maybe Law of Sines could be useful. So the Law of Sines, the Law of Sines. WebThe Law of Cosines says: c2 = a2 + b2 − 2ab cos (C) Put in the values we know: c2 = 82 + 112 − 2 × 8 × 11 × cos (37º) Do some calculations: c2 = 64 + 121 − 176 × 0.798… More calculations: c2 = 44.44... Take the square root: c = √44.44 = 6.67 to 2 decimal places Answer: c = 6.67 How to Remember How can you remember the formula?
