tan%28alpha%29=csc%282alpha%29-cot%282alpha+%29

since csc%282alpha%29=%281%2F2%29csc%28alpha%29%2Asec%28alpha%29 and cot%282alpha+%29=cot%28alpha%29%2F2+-+tan%28alpha%29%2F2

we have



.............csc%28alpha%29=1%2Fsin%28alpha%29 and sec%28alpha%29=1%2Fcos%28alpha%29, we have

.............cot%28alpha%29%2F2=cos%28alpha%29%2F%282+sin%28alpha%29%29











tan%28alpha%29=sin%28alpha%29%2F%282cos%28alpha%29%29+%2Btan%28alpha%29%2F2

tan%28alpha%29=%281%2F2%29%28sin%28alpha%29%2Fcos%28alpha%29%29+%2Btan%28alpha%29%2F2

tan%28alpha%29=tan%28alpha%29%2F2+%2Btan%28alpha%29%2F2

tan%28alpha%29=tan%28alpha%29
