Calculate the area between the curves ² = 16 sin 20 and ²: = 16 cos 20 .Show by drawing

10. Verify the following trigonometric identity: (secx – tanx)² 1– sinx 1 1 + sinx

From the graph we can determine the range of each sinusoidal function: a) For f(x)=2 sin x, R = b) For f(x)=-sinx, R = c) For f(x)=0.5 sin x, R =,

part a- Find the arclength along the circle of radius 5 from the point (5, 0) to the point at angle θ = 2.1.   part b- Find the coordinates of the point P at an angle of 7π/4 on the circle of radius 10.
