Normal and Tangent of Curve

[@masterjmyt8988]

Thankyou engr. Napakinabangan ko talaga

Nays, salamat engineer! 🤘

Good morning engr. Ask ko lang po if gumagamit po kayo ng shift integral sa calcu, palagi po ba dapat na naka radian mode? Or bawat may involve lang na trigonometric functions?

[@EngineerProfPH]

Hi engr. Yes po sa calcutech palaging nakaradian.😁

[@praiseworthy1999]

@@EngineerProfPH thank you po. Ask ko na lng din po pala if ano ang calculator na allowed gamitin for this upcoming feb board exam?

[@EngineerProfPH]

Casio 570 es plus po.😁

[@praiseworthy1999]

@@EngineerProfPH may 2nd edition na po pala ng 570 es plus. Ano po yung pwede, yung ginagamit niyo o yung 2nd edition. Thanks po.

[@EngineerProfPH]

Pwede po basta 570 es plus.😁 1st and 2nd

Ask ko lang po what if my slope is a fraction then po I will find the tangent equation, ano po yun pwede icancel ang denominator like in finding normal equation? Thank you po in advance for your response 😊

Hi.If the slope of your tangent line to the curve is m (dy/dx or y' @ certain value x), then the slope of the normal line which is perpendicular to the tangent line is the negative reciprocal, -1/m. Then using the point slope form. The equation of the tangent line is y - y1 = m(x-x1)= y'(x-x1) The normal line is y - y' = -1/m (x-x1) = -1/y' (x-x1) if the m or y' is a fraction, for example 1/2 therefore -1/m = -1/(1/2)= -2 ----> slope of the normal line

@@EngineerProfPH opo alam ko po yan.😅 what I am asking po is about the fraction slope then use only in tangent equation not in normal equation.

[@EngineerProfPH]

Ah ok po.😅 any fraction po or whole number, pwede maging value ng slope ng normal and tangent line. Depende po yan sa problem.

[@kuyakevz6714]

@@EngineerProfPH what if my slope po is in fraction form then po I'll just need to get the tangent equation, can I cancel it like doing in finding normal equation?😅

[@EngineerProfPH]

Pa input po ng problem..😁

May manual ploting ka sir ng curve?

[@adriprz_]

Wala na bang ibang example? Nakukulangan ako

[@lunaselenophile9956]

Nakailang nuod nako diko pa rin gets 😭

hello po engr., paano po ba to sagutin? f(x)=1-3x^2 is equal to 5 (find the tangent to the curve).
