WebMar 26, 2024 · For a less rigorous solution (presumably more suited for the SAT), recall that $\tan(\theta)$ is the slope of the line with angle $\theta$ in the unit circle and $\cos(\theta)$ is the x-coordinate of where that line intersects the unit circle. In the first quadrant, $\tan(\theta)$ would be greater than $1$ if $\theta>45^{\circ}$.
