WebA less insightful way to demonstrate this result is by showing, with the help of differential calculus, that the function c o s ( t) 2 + s i n ( t) 2 doesn't change over different t i.e. it's a constant function. then by plugging in any value, e.g. t = 0, c o s ( 0) 2 + s i n ( 0) 2 = 1 we arrive at the desired result.
