16 дек. 2015 г. · Everyone should know these factorisation formulae: 2cosacosb=cos(a−b)+cos(a+b)2sinasinb=cos(a−b)−cos(a+b)2sinacosb=sin(a−b)+sin(a+b). |
20 июл. 2019 г. · We know that sinx=siny implies that x=2kπ+y or x=2kπ+π−y. If we want to solve sinx=sinx using this method, it gives x=2kπ+x or x=2kπ+π−x but ... |
16 апр. 2018 г. · Calculate sin(x) over sin(y) ... where I know the values of a, b, α and β. How can I solve the equation for δ? ... Do you have the equation sin(x)=A ... |
1 сент. 2017 г. · Advice: You should remember the addition formulas to derive the multiplication formulas: sinx+siny=sin(a+b)+sin(a−b)=2sinacosb=2sinx+y2cosx−y2. |
10 окт. 2014 г. · Is Sin(x) + Sin(y) ... + Sin(n) = Sin(x+y...+n)? Is the same true for summation of cosines? I am making ... |
19 июл. 2018 г. · If you are looking at the universal statement: sin(x/y) is not equal to sin(x)/sin(y), for all x and y This statement is false. |
17 окт. 2016 г. · There is no general solution sin(x)/sin(y)=sin(z) (for all x,y). This can easily be seen by setting y=0 and then the fraction diverges ... |
2 апр. 2019 г. · Let A and B be as you defined. Then sin(A+B)=sin(x+y2+x−y2). Evaluate this and use the given identities. |
