Edexcel A level Maths: 8.1 Parametric Equations (Domain and Range)

[@isabellebowles3649]

I knew how to find the Cartesian equation but I found finding the domain and range difficult. The way you have taught it (using the graphs) have really helped

I LOVE THE ENERGY THIS GUY TEACHES WITH IT HELPS ENJOY THE LEARNING PROCESSSSSSSS

[@zeeshanzamurred9280]

Thanks 👍🏻

[@Sprintingsands]

im glad i found your videos yesterday, were really needed as we couldnt finish the course in time due to covid 19, you teach better than my teacher too hands down

4:39 Mmmhmm beautiful Cartesian equations.

[@nataliarobinson5671]

This helped soooo much. It was hard to get my head around first but I understand now with this video

[@Harry-h4e5y]

Your teaching is much better than my math teacher

Fantastic vid really appreciate it

[@jameslifts2196]

Quick and simple explanation, thanks brother

[@esharahman4648]

I love u man. U saved my life

[@sweetmaths4213]

When making t the subject...do I always have to have it in the form y= or could I rearrange the simpler of the two and still get the marks . Or could I make t the subject of both equations and just put them equal to each other? Love the speed of your delivery. Great teaching thank you.

Great teaching

[@drowninginyuqisdeepvoice8697]

AYO- THANK YOU SO MUCH 🙌🙌

[@danoneill1585]

For the second example, are we incorrect if we sub t from the y-equation into the x-equation (the opposite way to how you've done it)?

[@kevinprada7775]

Amazing!!

[@fatimahislam792]

Life saver 😊 thank you

[@antoniabarna6101]

life saver !!!!!!!!!!!!!!!!!!!!!!

[@elliottcooksey6886]

When converting to Cartesian form, can you do x= instead of y=?

[@7ssimz]

you are amazing keep this up omg

[@samiraazim]

THANKS SO MUCH :)

[@jiaminyang1931]

What if they ask you to leave a y=ax+b/x-1 form like this? What do you do?

[@ishitaverma5709]

Thank you so so much

How do you find the domain and range with out drawing a graph

[@sushruthravishankar2383]

legend..

[@eleanorcaffrey7662]

Should you always sketch the graph in order to find the range and domain?

[@ishqaqamar2789]

I've found that this helps make sure you're always correct. But in general, if you come across a quadratic equation for any of your parameters, just ascertain whether it's min or max from the sign of the coefficient of x^2 and use the derivative or whatever to find turning point. But I personally would draw it out for every thing, especially other polynomials and exponential functions

[@zoey3605]

2:10 how did you know this is the correct graph? im so lost

[@PrZz.z]

Bit late, but in the question they give u a reciprocal function (you know its a reciprocal function if its a fraction (one over x … ) ) so you draw a reciprocal graph and adjust it to match the function given in the question.

helped thank you

[@rasheede.o4824]

The solutions for a question similar to example 1 in your video doesn't state that x is any real number. Do you have to state x is any real number. I understand why and just want to clarify

[@zeeshanzamurred9280]

Rasheed E.O you wont lose a mark but, to be precise, it’s good to include x is any real number.
