Find two values for theta such that theta is greater than or equal to 0 but less than or equal to 2pi.

1. Tan theta=1.1071

2. Sin theta = -0.8818

1 answer

tan .836 = 1.1071
tanθ > 0 in QI, QIII
So, θ = 1.1071 or 1.1071+π

sin 1.080 = 0.8818
sinθ < 0 in QIII and QIV
So, θ = π+0.8818 or 2π-0.8818
