In the context of circles, a secant is a line that cuts the circle at two points.
P.S Got a new question SoulSearcher?

A particle's displacement is given by: x=3+2cos2t. Find
a) Initial displacement, velocity and acceleration
b) When the particle is first at rest
The question's in SoulSearcher's last post.Mc_Meaney said:Make it hard for me then. thanks riv
Question (i)SoulSearcher said:Let triangle ABC be right-angled at C, so a2 + b2 = c2. Find the ratio c : a if:
i) b is the arithmetic mean of a and c
ii) b is the geometric mean of a and c
Sorry, I didn't have any time, I have my trials today, doing maths was my break from English study (can English really be that bad?). I will post one later today but anybody may feel free to beat me to it.SoulSearcher said:I would like a question that I can do at the dead of night Sober
Yes it can beSober said:can English really be that bad?
For this question, we will have to consider 2 areas; the area of the equilateral triangle formed by joining the centre of each circle to each other, and the area of the segments that remain in the shaded area.Sober said:Three circles, each of radius r are placed so that the center of any circle lies on the circumference of the other two circles. What is the area where all three circles overlap?
For those interested the name of the resulting shape is a reuleaux triangle.

The temp T*Celsius of a compount in a science experiment is increasing exponentially over t minutes such that dT/dt = 0.03T. The temp was initially 23*C
(a) By what percentage is the tempterature increasing each minute?
(b) What is the temp after 10 minutes?
(c) When does the temp reach 100*C
