Critical_Fallacy, I do wonder how can you think in such brilliant ways of solving mathematical problems? In ways that usually people would not thought of yet effective. Is it with sufficient practise or critical thinking? Just asking only biggrin.gif
If I have come up with effective tactical solutions, it is by fighting on the shoulders of Titans! flex.gif

Hi Flame Haze, RED-HAIR-SHANKS, maximR, crazywing26 and v1n0d,

Can you simplify this equation? sweat.gif

Wow, this is simply stunning! It discombobulated me momentarily and even I have no idea on where to start to simplify it. But, I'd like to see if anybody else can post the correct workings. rclxms.gif

By the way, I can tell that roughly all of the terms in the equation is unknown, but, other than omega itself(ω), does the Η, N and Y is an unknown too, or are they a part of the Greek alphabet? unsure.gif

I guess that we can replace H(Eta) with 8, N(Nu) with 50, and Y(Upsilon)with the value of 400 since each of those 3 alphabets has it's own value in the Greek numerals. Because, if we just treat them as an unknown, then the equation will be harder to simplify compared with the presence of a few numerical values.

Mostly I'm wrong, but, anybody willing to correct me and guide me in this question?

Critical_Fallacy I don't think I can , but I'll leave it to the others to come up with a simplification . biggrin.gif

I've been away to study STPM Kinematics and Dynamics . I must say that STPM Physics is on a whole new level compared with SPM Physics . Here's one question which I need help on :

Two objects with masses m1 and m2 have the same kinetic energy . What is the ratio of the momentum of mass m1 to momentum of mass m2 ?

- On a sidenote , I've finally studied Sequences and Series using sigma notation and only now do I comprehend the posts about formulae for the series of squares , cubes , etc . And I saw many cool tricks to come up with a simple formula for a sequence !

I'd like to get First Term and Second Term STPM Maths T books alongside your printed tutorials and start working on them , if I can finish those I think I'd be ready for A Level Maths and a little bit of A Level Further Maths .

Wow, give yourself a pat on the back! thumbup.gif I've never though the final simplified answer would be something like this, and I ridiculously thought of something concerning Greek numerical and other non-related stuff.

Haha! Looking at the choice of variables and your previous 2013 question, I figured it'd be a new year wish!
Looks like ystiang has beat me to the answer though. blush.gif

That is not the Total Area, or specifically, your triangle area of the side of the pyramid is incorrect!

u mean the total surface area only consists of 4 side of the pyramid? but not the base area? sweat.gif

Yes , this took the most time as I had to play with the equations and think about the different cases for the concepts to sink in . For example , the object that is projected at an angle doesn't accelerate in the horizontal direction at all . Another thing which I want to point out ( which is incorrectly stated in SPM ) is about the sign of g in kinematic problems .
