Sin 20 = A x / 145 A x = 49.6 m Cos 35 = B x /105 B x = 86.0 m A x + B x = 135.6 m

A jogger runs 145m in a direction 20.0 degrees east of north (vector A), and then runs 105m in a direction 35.0 degrees south of east (vector B). Using components, determine the magnitude and direction of the resultant vector C for these two displacements.

( cos  + i sin) 3 = ( cos  + i sin) ( cos  + i sin) ( cos  + i sin)

To Prove: Cos 3  =c os 3  - 3 sin 2  cos  and Sin3  = sin  - 4 sin 3 . Proof:. ( cos  + i sin) 3 = ( cos  + i sin) ( cos  + i sin) ( cos  + i sin). = ( cos 2  + i sin cos  + i sin  cos  + i 2 sin 2 )( cos  + i sin).

Simplify cos (sin −1 x ) and tan(sin −1 x ).

To compute the derivatives of the inverse trigonometric functions, we will need to simplify composite expressions such as cos (sin −1 x ) and tan(sec −1 x ). This can be done in two ways: by referring to the appropriate right triangle or by using trigonometric identities.

y = a sin b x + d or y = a cos b x + d

y = a sin b x + d or y = a cos b x + d. a = amplitude: Max – Min (sin starts in middle of the max & min) 2 (cos starts at the max or min). b = frequency: # of waves you see between 0  2  We can use the period formula to find frequency. period = 2  b.
