Hi,
I'm working on a problem about a spherical balloon as its inflated slowly the radius of the balloon is in cm and the time is in seconds
dr/dt = k/r2
Now I know how to rearrange this equation using separable differentiation
r=3√3kt+c
However I would like to find the value of the...
Hi,
I just want to make sure I understand acceleration
α = Δv / Δt
α = vf - vi / tf - ti
α = 8m - 0m / 4s - 0s
α = 8m / 4s
α = 2 m/s2
So I know it has a constant acceleration of 2 m/s2
what I want to know does this mean that the object will increase in acceleration for...
Hi,
This may sound a little silly but I have a circuit with 1 resistor which is a 1k ohm resistor
and is connected to a 9 Volt battery.I found the amps using ohm's law I = E/R which equals 9 amps.I have also used a multi-meter to see the resistance and I'm a bit confused a resistor is...
Hi,
I'm trying to find the amp of a circuit. Okay I know a circuit has a resistivity, So for example if my circuit is made out of cooper which has a resistivity of 1.68 * 10 negative power of 8 and a voltage of 9 volts.So do I just use ohms law Volt / Resistant = Amp?
Yes I understand Soh Cah Toa but I am using the equation to find the side of an unknown
side and the formula I'm using is
Example
tan = opposite / adjacent
but I only have the opposite side and the angle so to find the adjacent side I used this formula
24 / tan 42 degrees =...
Hi,
I'm a bit curious on how do I find the length of the Opposite side of a Right Triangle,
now I have look a Soh Cah Toa, Now say if I know the length of the Adjacent Line and the the angle of the right triangle which formula should I use?
I thought about Toa is this the way I solve...
hi,
because in Java programming the x coordinates travel across the screen and the y coordinates travel down the screen so when I use the formula y2 - y1 then we are travelling
up the screen which gives us negative 200
Hi,
I don't no what you mean by figure?
but here is what I have done
sideA = x2 - x1 which equals 200pixels
sideB = y2 - y1 which equals -200pixels
angle = inverse tan = sideB / sideA
angle is -0.7853981633974483 in radians
find the X component
sideC = sideA / cos( angle )...
sideA = adjacent
sideB = opposite
sideC = hypotenese
Find Angle
angle = inverse tan = sideB / sideA
Find side
find the X component
sideC = sideA / cos( angle )
find the Y Component
sideC = sideB / sin( angle )
I think I got the formula wrote the wrong way but now my...
sideA = adjacent
sideB = opposite
sideC = hypotenese
Find Angle
angle = inverse tan = sideA / sideB
Find side
find the X component
sideC = cos( angle ) * sideA
find the Y Component
sideC = sin( angle ) * sideB
So my question is is how or why is my hypotenese line being...
Hi,
You are correct I don't no why my calculator is giving me
0.29636857870938531739229664984902
but when I tested the same equation in java programming,java gives me the answer you gave
sin(38) = 0.2963686
120 * sin(38) = 35.56423
So what would this formula be good for?
Hi,
I have a question I have learn a bit about trigonometry and I came across this formula
angle = 38
length = 120
formula
length * sin( angle )
now I have look around for the understanding about this formula and tested the formula my self...
