Tan^2x + 1 + tanx - 3 = 0 tan^2x + tanx - 2 = 0 (tanx + 2)(tanx - 1) = 0 tanx = -2 or tanx = 1 x = 2.034 radians or x = 5.176 radians or x = pi/4 radians or x = 5pi/4 radians
To set up the integral in sphericals, just draw a picture. The limit in θ is determined by
<span>cosθ=R−h/R</span>
Therefore, the volume of the cap is the integral
2π∫↓0↑arccos[(R-h)/R] dθ sinθ ∫↓(R-h) /cos<span>θ </span>↑R dr r²
Need help myself not sure sorry
9.5 per square yard.
since total square yard is 12, 9.5 × 12 (per 1 × 12 square yard.)
so 9.5 × 12 = $114.
