Question

Can someone simplfy to me why we use different formula in some equations for sin cos tan? Like in some instances we swap variables and in others we just divide and stuff and I don't understand why we do that ​

Answer 1

It does get confusing but there are ways to try & differentiate what is divided & what multiplied or added & subtracted when using variables wording plays a big part in what needs done. Depending what the equation is asking for. Pay close attention to the wording in each one
