A student wanting to catch fish to sell at a local market on Sunday has discovered that more fish are in the water at the end of the pier when the depth of water is greater than 8.5 metres.

 

The depth of the water (in metres) is given by d=7+3*sin((π/6)t), where t hours is the number of hours after midnight on Friday.

 

a. Between what hours should the student be on the pier in order to catch the most fish?

b. If the student can fish for only two hours at a time, when should she fish in order to sell the freshest fish at the market from 10.00am on Sunday monday?

what kind of fish, some fish move to shallow waters when it's feeding time, usually early morning and late evenings.

some time boils are created during the feeding frenzy, that's when to catch fish,but that occurs during spawning season. you can just throw a hook in the middle of the boils and catch a fish effortlessly, if you have a multi rig set up, you can catch more than one.

 

other than that,

i'm not sure what all that other stuff is for,

in a simple answer,

fish saturday night at the 8.5 m depth.

simple.

Simple and wrong. It is just a maths question. A sine wave is periodic (every 2pi radians) - multiplying the time(in hours after midnight) by pi/6 means you will get two peaks every 24 hours; this is a rough approximation of tides. It is a trigonometrical inequality - for what values of t is d>8.5.

I understand the math problem.

but the reality is not the math problem.

fish and fishing are just that.

fish behave in a character that math does not pertain to( in a sense).

 

when you get into fishing, bass/trout/deep sea or such,

you learn this.

Who cares? It's a math problem, and the point is application (realistic or not). John bought 200 apples, then proceeded to eat 70 of them. Oh look, John now has 130 apples.

Don't forget about Joe the track runner.

 

Joe is doing a quick sprint. If Joe is 6 feet tall running at a sprinting steep of 75 degrees elevation, approximately how far will Joe's face travel if he trips and faceplants into the ground? (assume no gliding / air time)
