If sin tita = cos tita find tita between 0° and 30°
1 answer:
Answer:
there is no solution for (0, 30°)
Step-by-step explanation:
six(x) = cos(x)
sin(x) - cos(x) = 0
(sin(x) - cos(x))^2 = 0
sin(t)^2 + cos(x)^2 - 2sin(x)cos(x) = 0
1 - sin(2x) = 0
sin(2x) = 1
2x = π/2 + 2πk -> k - any integer number
x = π/4 + πk
the smallest positive solution is π/4 = 45°. That means for range (0, 30°)
there is no solution
