For the Euler Axis and Principal Angle, demonstrate that: DCM° = cos O, + sin Ov2 VDCM° = – sin Ov, + cos Ov,

A baseball hit just above the ground leaves the bat at 24 m/s at 45 degrees above the horizontal. How far away does the ball strike the ground? Can you visually show the above.  It has to do with right angles and trigonometric functions, but I need your explanation to understand how this works, as I am new to this.

Find the angle h for the sun in the following positions 1)the inclination of the sun d=-20° regardless of the effects of the atmosphere and the size of the sun? 2)the desire of the sun d=20° considering the effects of the atmosphere and the size of the sun?

I am pretty sure that this can be solved by adding 57 to mg cos(theta) but when I enter -59.196 into the problem it says that it is incorrect.
