1) To find the value of y when x = π/3 for the equation y = -cosx + 2:
y = -cos(π/3) + 2y = -(1/2) + 2y = 2 - 1/2y = 1.5
Therefore, when x = π/3, y = 1.5.
2) To find the value of y when x = -π/4 for the equation y = tanx + 4:
y = tan(-π/4) + 4y = -1 + 4y = 3
Therefore, when x = -π/4, y = 3.
1) To find the value of y when x = π/3 for the equation y = -cosx + 2:
y = -cos(π/3) + 2
y = -(1/2) + 2
y = 2 - 1/2
y = 1.5
Therefore, when x = π/3, y = 1.5.
2) To find the value of y when x = -π/4 for the equation y = tanx + 4:
y = tan(-π/4) + 4
y = -1 + 4
y = 3
Therefore, when x = -π/4, y = 3.
