Ah thank god. Thanks for confirming for me. Else I would have been spending the whole day trying to figure out why there is a 15 there haha. This is the first time seeing a mistake in this textbook. But I guess things like this happen

So I am supposed to look at the graph at part C and determine the total distance travelled. This is the answer sheet of the textbook. But I feel like the textbook is wrong here. But then I needed a confirmation if others can agree that it is wrong or not cause now I am very confused. My answer...

I am really bad at visualizing things so I was not able to visualize what he said :frown:

Thank you! I was able to do it, although it was pretty long. Sorry if the workings look unclear. Was wondering since it was pretty long if there is a shorter way of doing this?(Excluding using the formula I mentioned) I mean like I might have used some extra unnecessary steps here Any steps that...

I just simply used the formula to solve. Note the "x" represents multiplication in this case 0.5 x a x c Sin B This is based on the conditions given in the textbook I am using which quotes "Use this formula to find the area of any triangle when you know 2 sides and an angle between them" So I...

Thanks guys I have got it now. Replying to Delta: Yeah Trigonometry really confuses me a lot. I can solve normal equations but when it comes to Trig I just go blank. Specially when it comes to manipulating equations and all Replying to Orodruin: Thank you for your explanation. I think I got...

Ahh I see thank you. I am still at very basic level of trigonometry but I understand more now So in this case I should do sine inverse to solve for 6.4sine(24) right? Or should I divide both sides by 7 sine ? Both seems to give similar answers which is where I am stuck at, hence my original problem

I apologize for that. The reason I included just the equation is to know which method is best to solve for trigonometric equations. Whether to use Sine inverse to solve for X, or to divide both sides by Sine 7 I only had problems with solving that equation and wanted to know that and not the...

I understand that yeah. I did apply that equation and arrived at Sin7x= Sin24 * 6.4 At this point I was having a problem whether to use inverse sine after dividing both sides by 7 to solve for X OR To divide both sides by Sine 7 to solve for X Because both seems to be giving similar answers but...

Hello yeah these are in degrees Here is the question, sorry i did not post it before Using Sine rule I did: Sin x/ 6.4= Sin60 * 7 But at the final part I was not sure if I should use inverse sine to solve X or divide both sides by sine 7 to solve X

So I came across a question regarding sine rule. This is to find a missing angle. The question goes as follows Sin7x= Sin24 * 6.4 I tried two methods to solve this. Method 1: x= (Sin24 * 6.4)/ Sin 7 =21.35 I basically divided both sides by Sin 7 Method 2: Sin x= (Sin 24 * 6.4)/ 7 x=...

Yeah S/2. The question I copy pasted somehow didnt include the slash. Also how does the "s" and "a" disappear just like that in the last expression you made. That part is a bit confusing. I do understand the 1st step now though which you made t the subject of the formula.

Question: Galileo released a metal ball from rest so that it could roll down a smooth inclined plane. The time t taken to roll a distance s was measured. He repeated the experiment, each time recording the time taken to travel a different fraction of the distance s. Write an expression for the...

Actually I do understand question A and B here. But I am struggling to understand why there is a 1.75A in the diagram. Is that maybe the combined current for E2 and E1? If so then I think I understand. The reason I was struggling is that I am not 100% sure if 1.75A is just the current for E1 or...

Isn't the first law about currents dividing. Basically I1=I2+I3 But since we are finding the EMF of the battery, shouldn't we use the total current, therefore I1? In other words shouldn't the current BEFORE it splits be the actual current transferred by the battery E1? That is the reason why I...
