| Hello, I have the following wave.. 4 cos(3 theta)-6 sin(3 theta) ...and express it in the following form... *R*sin(3 theta + beta) I'd be grateful if anyone can explain how to do this in Wolfram|Alpha? (BTW - I have typed theta and... |
| Hello, Can anyone tell me how to get WA to factorise and show steps for this... 3sin^2 (t) + 2 sin(t) − 1 = 0 into this... (3 sin(t) − 1)(sin(t) + 1) = 0 Thanks in advance, Ian |
| Hello, I'd like to know how I should input formulae for transposition in Wolfram|Alpha and would be grateful for some help. I can do this in Mathway, but I'm finding Wolfram|Alpha less easy to use. Ian |
| Is it possible to get simultaneous equations solutions, with steps, from Wolfram|Alpha? I have tried without success and may be inputting it incorrectly. |
