so i took calc 1 when i was a senior in high school and im a junior in college now...so i've forgotton some of the differentiation rules... my question is, when you differentiate e^x the answer is e^x, but what if you are differentiating e^(1/x)? do you follow the rule where you have d a^x/dx =ln(a)*a^x? Thanks!

This is a physics related questioan. I could only find what happen to the light when it travels thru the eye. my questioan is how does the nerve impulse propagates to the brain in a physics way.I only could find the biology term of it. It's a presantation in my class and it 5% of my total course mark. Could anyone just leave some webpage or anything that icould use. I don't want my presantation to be to complicated a simple but good information would be nice. Thank you very much.

1) A police car leave sin pursuit of a hold up car 0.50 h after the latter has left the crime at 75 mi/h. How fast must the police go if it is to catch up with the hold up car in 1h?

2) A snake is slithering toward you at 1.5 m/s. If you start walking when it is 5m away, how fast must you go in order that the snake not overtakes you when you had gone 40 m?

3) A hare and a tortoise compete in a race over a course 1.0 km long. The tortoise crawls straight and steadily at its maximum speed of 0.2 m/s toward the finish line. The hare runs at its maximum speed of 8.0 m/s toward the goal for 0.8 km and then stops to tease the tortoise. How close to the goal can the hare let the tortoise approach before resuming the race, which the tortoise wins in a photo finish? Assume that, when moving, both animals move steadily at their respective maximum speeds.

Thanks to those who'll be helping me.. I really don't know how to solve these physics problems..
