Answer:
sinѲ - cosѲ =
Step-by-step explanation:
sinѲ+cosѲ=m ----(1)
lets consider: sin0-cos0=n ------(2)
square the 1st equation: Ѳ +
Ѳ + 2sinѲcosѲ =
-----(3)
square the 2nd equation: Ѳ +
Ѳ - 2sinѲcosѲ =
------(4)
Add 3rd and 4th equation:
= Ѳ+
Ѳ+
Ѳ+
Ѳ=
+
Since Ѳ+
Ѳ=1
===> 1 + 1 = +
===> 2 = +
===> =
+2
===> n =
since sinѲ - cosѲ = n
Therefore sinѲ - cosѲ =
