the projection of v into the direction of u 0k that's why :) thanks

F parallel hat= (F hat) * (r hat / r)

Hi everyone( the force vector parallel to the position vector r ) = Force vector* (r vector / r) I don't know how did they find this relation ? it seems to me they multiplied F hat by the unit vector ? why ?? I am just confused about it any idea ??

I got the answer :D >> thank u : )

how can I know the second point of the limit integration ?!

also, there is a triangle region under x-axis between 1 and 2 but I think it is not included in the intersection

they intersect between 1 and ( a unknown point intersection between 2 Sqrt x and x = 1 )

yeah I did sketched the three curves then ?..

I did not try ..because I am not familiar with the way of solving

Hi VVVVVV Find the centroid of the region bounded by the curves y = 2x - 4 , y = 2 Sqr x, and x = 1. Make a sketch of the region.

I do not know how I can remove the read line under the power A and bclc clear handle = COM_OpenNXT(); COM_SetDefaultNXT(handle); OpenSwitch(SENSOR_1); x = 1; power=50; foreverLoop= 1; loop = 1; Kp = 1000; offset = 45; Tp = 25; error = 0; powerA = 0; powerB = 0; degrees=360; powerA = Tp + Turn...

I am supposed to program the Lego to follow the line smoothly here are some information .. --------------------------------PURPOSE: To utilize the LEGO NXT block as an interface to gather input from feedback mechanisms (touch sensor, light sensor, ultrasonic sensor, etc.), make sound, display a...

yeah, there are errors and read lines under defined powers

Hi Controlling the LEGO NXT Using MatLab What are my mistakes in this code ??! COM_CloseNXT all clc clear handle = COM_OpenNXT(); COM_SetDefaultNXT(handle); COM_CloseNXT(handle); NXT_GetBatteryLevel(handle); COM_CloseNXT(handle); COM_CloseNXT all clc clear...
