write tan in the form of cos and sin and then take LCM
= (cos sqA - sin sq A)/ (cos sq A + sin sq A)
cos sq A + sin sqA = 1.
cos sq A = 1- sin sq A
so we can write
1- sin sq A - sin sq A
= 1- 2 sin sq A
= (cos sqA - sin sq A)/ (cos sq A + sin sq A)
cos sq A + sin sqA = 1.
cos sq A = 1- sin sq A
so we can write
1- sin sq A - sin sq A
= 1- 2 sin sq A
