See Fig. In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true. The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics.

In mathematics, algebra a motorboat whose speed in still water is queen one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

So if you look at our diagram, we know that A Motorboat Whose Speed In Still Water Is Update the river is m wide and the pilot must land the boat at a point of m upstream from where it begins. So we call the vertical axis are Y access and the direction which the river flows that is right to left as our X axis. So the first thing we need to do is calculate this angle, Peter. Now detail we can see from our diagram is the up 10 off over m and so we get an angle data off 22 0. Now we want to equate the vertical components off the velocities to find the speed of the boat relative to the shore.

So the speed of the border to the shore. So we're calculating the speed. That's the subscript bs for both relative to shore times, the co sign off data is equal to the speed of the boat relative to the water. The VW Times the sign off 45 degrees. So, using some trigonometry, we can rearrange this and we confined the speed of the board relative to the shore.

And this gives us the speed of the boat relative to the shore to be 1. Now we want to calculate the horizontal components off the velocities. So the speed off the boat relative to be short times ST Peter was equal to the speed of the board relative to the water. So, rearranging this equation, we get the W s, which is the speed off the current off the river is equal to V the W co sign 45 degrees minus the the S sign off Tita which is And so if we substitute our bodies into this, forget this a motorboat whose speed in still water is queen be one 0.
