Trigonometric EquationIf in a triangle, Then, What is the value of sin angle A? Is it 8/27? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #2 20130323 19:20:56
Re: Trigonometric Equationhi Agnishom So I put and rearranged to get Different values of k will make different sized circles but all the resulting triangles will be similar => same three angles. So it is ok to take a = √6, b = 2√2, c = 3√3 Use the cosine rule to get cosA and hence sinA. I made it Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #3 20130323 19:38:29
Re: Trigonometric Equation
I have the following doubts: 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Trigonometric EquationOkay thanks I managed to understand this 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Trigonometric EquationYeah Thanks! I had difficulty understanding the cancellation 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun.

Re: Trigonometric EquationTwo triangles with sides in the same ratio are similar. So the angles are the same. Therefore you can just call t = 1 without losing any of the problem's conditions. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei
