Find value of c(a point in f(x) where slope of tangent to curve is zero) wheref(x) = \(\begin{cases}Tan(x) & 0

• A. π⁄4
• B. Rolle’s Theorem is not applied, because function is not continuous in interval [0, π⁄2]
• C. Rolle’s Theorem is not applied, because function is not differential in interval (0, π⁄2)
• D. Function is both continuous and differentiable but Rolle’s theorem is not applicable as f(0) ≠ f(π⁄2)
