object, and what is the linear speed ν of the object? Here give the exact value of the item followed by its decimal approximation. ω = ν = 7. (5 pts.) If θ is an acute angle, and sin( θ ) = 1/3, obtain the exact values for the remaining five trigonometric functions. tan( θ ) = cot( θ ) = sec( θ ) = csc( θ ) = cos( θ ) = 8. (5 pts.) If the point (4 ,-5) is on the terminal side of an angle θ , obtain the exact value of each of the six trigonometric functions of θ . sin( θ ) = cos( θ ) = tan( θ ) = cot( θ ) = sec( θ ) = csc( θ ) = 9.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
