Ask lang po ako about po sa number 2 example po ninyo for the tangent line po, Diba po dapat ma -6x sya kung ililipat sa kabila po? ask lang hehehheheh

[Artemis-cupt]

Sa 8:01 diba dapat po yung Tangent Line 2 is 4x + y = -1?

[karlrusselmanduriao]

Sir sa problem #4 . Solution po nung normal line when they both multiplied by 14, di po ba magiging

[ y + 1/2 = (-8/7)( x + 2 )](14) 14y + 7 = -16x - 32 ?? medyo na confuse lang po. Correct me if I'm wrong po. Thank you

Sir in your first example. For solving the tangent line
How did y-2=4(x-1) become 4x-2? Where did the -2 come from?

[paulbrugoy_gamer]

Dami mong shortcut sir pano maintindihan yung sagot

[daylcambal]

How about po if hindi given ang points then ang equation (not the tangent equation) is may y and x. How to solve that sir??
