Show that cos3t equals 4cos cubed t - 3cos t?
cos(3t) = cos(2t + t) = cos(2t)*cos(t) - sin(2t)*sin(t) = [cos2(t) - sin2(t)]*cos(t) - 2*cos(t)*sin(t)*sin(t) = [cos2(t) - sin2(t)]*cos(t) - 2*cos(t)*sin2(t) then, since sin2(t) = 1 - cos2(t) = [2*cos2(t) - 1]*cos(t) - 2*cos(t)*[1 - cos2(t)] = 2*cos3(t) - cos(t) - 2*cos(t) + 2*cos3(t) = 4*cos3(t) - 3*cos(t)
Find the value in the equation of T plus 5 plus 3T equal 1?
T + 5 + 3T = 1 Simplify the terms, T and 3T (think 1 apple plus 3 apples) 4T + 5 = 1 Subtract 5 from both sides. 4T = -4 then divide both sides by 4 to get T by itself. T = -4/4 T = -1 To check, substitute T = -1 wherever you see T in your original equation. T + 5 + 3T = 1 (-1) + 5 + 3(-1) = 1 4 - 3 = 1 1 = 1 (check)
What is the shape of graph for simple pendulum between L and T?
T = 2*pi*sqrt(l/g) where g is acceleration due to gravity. So T is proportional to sqrt(l).Since both must be positive, the graph of T against L is the shape of the positive square root function.T = 2*pi*sqrt(l/g) where g is acceleration due to gravity. So T is proportional to sqrt(l).Since both must be positive, the graph of T against L is the shape of the positive square root function.T = 2*pi*sqrt(l/g) where g is acceleration due to gravity.

How do you solve 3 sin theta 1.5 when 0 isless than or equal to theta which is less than or equal to 4 radians?
I am assuming that the equation is 3*sin(t) = 1.5 even though the equality sign is not visible - due to the browser limitations. Then sin(t) = 1.5/3 = 0.5 So t = sin-1(0.5) which gives the principal value of t = 0.5236. The next value of t, in the domain, is pi - 0.5236 = 2.618 radians. There are no further values in the specified domain.
Is 18000 lb greater than 9 t?
No. Convert to same units then compare: * If by ton you mean long ton (as used in UK): 1 t = 2240 lb → 9 t = 9 x 2240 lb = 20160 lb > 18000 lb * If by ton you mean short ton (as used in USA): 1 t = 2000 lb → 9 t = 9 x 2000 lb = 18000lb which is not greater than 18000 lb as it is equal to 18000 lb. Either way 18000 lb is not greater than 9 t.
Which is bigger 18000 lb or 9 t?

18000 lbs 1 US (short) ton = 2000 lb 1 UK (long) ton = 2240 lb 1 tonne (metric) = 2204.6 lb
Is 18000 lbs bigger than 9 t?
They are equivalent.
Is 16T greater than 32000 Lbs?
It depends which ton you mean by 16T:Short (US) ton1 short ton = 2000 lb → 16 t = 16 × 2000 lb = 32,000lb→ 16 t and 32,000 lb are equalLong (UK) ton1 long ton = 2240 lb → 16 t = 16 × 2240 lb = 35,840 lb→ 16 t are greater than 32,000 lbMetric ton (tonne)1 tonne = 1,000 kg ≈ 2205 lb (not far short of the long ton) → 16 t = 16 × 1,000 kg = 16,000 kg ≈ 35,274 lb→ 16 t are greater than 32,000 lbOverall, 16 t is greater than or equal to 32,000 lb.
How many pounds does nine tons equal?
