As stated above, the law of cosines in trigonometry generalizes the Pythagorean theorem. If you plug 90º for the angle in one of the rules, what will happen? Since cos 90º = 0, we are left with the Pythagoras theorem. The law of cosine is also known as the cosine rule.

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?
