Learning math takes practice, lots of practice. Just like running, it takes practice and In any triangle we have: 1 - The sine law sin A / a = sin B / b = sin C / c 2 - The cosine laws a 2 = b 2 + c 2 - 2 b c cos A b 2 = a 2 + c 2 - 2 a c cos B c 2 = a 2 + b 2 - 2 a b cos C Relations Between Trigonometric Functions Från detta kan sin, cos och tan för vinkeln 45° beräknas då Pythagoras sats ger hypotenusan c = √(a 2 + b 2) = √2 Därför gäller, Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history 2008-12-29 · The simple solution, by inspection, is to remember that sinx = cosx = sqrt(2)/2 when x = pi/4. As others have pointed out, this also applies to an infinite number of real values given by pi/4 + 2npi, where n is any integer.
