in a sine curve, evry y value has two x values. wen u find an angle usin sine, dere r two possible values for dat angle, but our calculator shows only one value. to find da other value, we use sin x = sin(180-x).
similarly, in a cos curve, dere r two angles wen u use cos to find an angle. to find da other angle, we use cos x=-cos(180-x)

Hi, how r u??
How was ur exam?...BTW wish u all the best!!!
Anyhow.. I want to know a question about biology. paper 6.....how I know which is for the x axis and which is for the y axis in graphs for e.g time and temperature, sme time y is for time and smtime x is for time so I'm really confused.

i'm fyn, thnk u. wbu?
my xams wnt well, alhamdulillah! thnx, n same 2 u!
regardin ur question..., da variable dat u chnge is always da x-axis, n da other is 4 da y-axis. or else, dey myt giv which is which!

exam was so easy, thanks for ur help...BTW u mean that time is always on x axis

no, if u wnt 2 measure da rate of photosynthesis wen temp chnges, 4 an example, u chnge temp, ryt? so temp is da x-axis, n da rate of photosynthesis is da y-axis.

ya but sme of my friends tell me that the first column should bethe x axis what ever it is time,..etc...so is this correct what they say and sme say that time (independent) should always be on the x axis so u know whats my point..
