Quick check? Thank You for helping! Use the formula v1*v2=|v1||v2|cos theta to find the cosine of the angle between the two vectors (-7,8) and (1,0). I got cos theta=-7/10.63. Is this correct? Thanks!

    Cool, so from there I can take the inverse and get what theta is?

    @Notsephirorth For this kind of calculations, it is best to leave the radical sqrt(113) because it is the exact value. 10.63 is only an approximation to sqrt(113).

    @mathmate Thanks for the advice. Unfortunately I already submitted the assignment. Thanks though!
