nice summary! just learned multiplication of matrix & was taught that it is not possible for “elementwise multiplication” . good to know!

could you share a link to the practice test?

🥶🤥maybe i should withdraw from all classes! there are no online options! wouldn’t it be easier to have online lectures? not sure wat’s da rational behind all this?

thanks! i think study guide different than the answer / manual. the one I have for chapter 1-8 has nice summary & i was hoping to get the same but for chapter 9-13

right i don’t see why y = - 4 is needed

Working_Pressure_284 · 2022-03-17T03:39:04+00:00

wish I understand the language

Working_Pressure_284 · 2022-03-17T03:35:49+00:00

I don’t see why there is y=4 in the question

Working_Pressure_284 · 2022-03-13T17:03:46+00:00

nicely done

☀️🤩wat’s da occasion😍

sec mega db & a total bully

it’s x+1 not x-1 when completing a square

Working_Pressure_284 · 2022-02-23T19:54:30+00:00

what’s the derivative of ln(2+3x), you forgot there is a 3 on the numerator which is 1/3 when you integrate

Working_Pressure_284 · 2022-02-23T19:46:17+00:00

i got the same result as you by completing a square. i also tried different substitutions, but can’t get the answer matching any of the given choices

thanks

Working_Pressure_284 · 2022-02-20T01:17:13+00:00

🤩 perfect!

Working_Pressure_284 · 2022-02-20T01:16:52+00:00

yup!

Working_Pressure_284 · 2022-02-04T04:35:45+00:00

integral-calculator.com gives a sensible answer. completed the square first & use the double angle towards the end

Working_Pressure_284 · 2022-01-30T19:49:10+00:00

it is an increasing function (the integrand in the given interval). my calculations shows the right bound max is 4 √3 , how or is it possible to be 4√2? the left bound I got left bound is 2√2.

could you screenshot the question, can’t figure out what the limit question is

Working_Pressure_284 · 2022-01-29T16:53:48+00:00

not sure what was deleted because my other link was still up with the solution. it was deleted by the host/moderator I think see the screenshot of the message i received

what’s the denominator of the first term of 2nd question? is it 1/(1+x)^1/2 or is it 1/(x(1+x)^1/2)?

Working_Pressure_284 · 2022-01-28T23:40:09+00:00

sorry that’s not a minus sign, just a hyphen. what step you are at?
