cos^2(60)+cos^2(45)+cos^2(x)=1

cos^{2} (60) + cos^{2} (45) + cos^{2} (x) = 1

No Solution for x \in R

Solution steps

cos^{2} (60) + cos^{2} (45) + cos^{2} (x) = 1

Solve by substitution

cos (x) = i - 1 + cos^{2} (60) + cos^{2} (45), cos (x) = - i - 1 + cos^{2} (60) + cos^{2} (45)

cos (x) = i - 1 + cos^{2} (60) + cos^{2} (45) :

No Solution

cos (x) = - i - 1 + cos^{2} (60) + cos^{2} (45) :

No Solution
