What is the diff between average velocity and instantaneous velocity? Which is more important? Give the eq for each

What is the diff between average velocity and instantaneous velocity? Which is more important? Give the eq for each

Answer: Average velocity is the change in displacement over a period of time (delta x / delta t). Instantaneous velocity is the displacement for a specific moment in time so a specific time eg. t=5s will be given (delta x /t)

Answer: cos^2theta + sin^2theta=1

Write out the chart for common angles and their sin and cosines?

Write out the chart for common angles and their sin and cosines?

Answer:


Column 1 (Angles)= 0,30,45,60,90
Column 2 (Sines)= 0 over 2 (0), Square root 1 over 2 (0.5), Sq rt 2 over 2 (0.7), Sq rt 3 over 2 (0.9), Sq rt 4 over 2 (1.0)
Column 3 (Cosines) = Vice Versa
