\text{Let } P_1(1+\cos t,; \sin t)\text{ be a point moving on the circle with center } (1,0)\text{ and radius } 1,]Both points start at the intersection point of the two circlesand move counterclockwise along their respective circles.Assume that their speeds satisfyLet be the time when the distance between and is maximized.At this moment, the following expression:where and are relatively prime positive integers.Find the value of .oindent
[THOUGHT] After analyzing, substitute theta = 2t due to the 1:4 speed ratio. Compute the distance squared substitution, derive with respect to t. Find t₀, plug back into expression. Reduce fractional result. Error handling included. [/THOUGHT]```python import sympy as sp
Define variables and equations
t, theta = sp.symbols(r't theta')
Positions
p1_x = 1 + sp.cos(t) p1_y = sp.sin(t)
p2_x = 2sp.cos(theta) p2_y = 2sp.sin(theta)
distance_sq = (p2_x - p1_x)**2 + (p2_y - p1_y)**2
Angular relationship due to speed ratio
Speeds' ratio v1/v2=1/4, hence omega1/r1 = omega2/r2 gives omega2=2 omega1
Thus, theta = 2t
substituted_distance_sq = distance_sq.subs(theta, 2*t)
Take derivative w.r.t t and set to zero
derivative = sp.diff(substituted_distance_sq, t) critical_point = sp.solve(derivative, t)
Calculate the target expression at critical t
expression = 2*(sp.sin(t) * sp.sin(theta) - (1 + sp.cos(t))sp.cos(theta)) expr_at_t0 = expression.subs(theta, 2t)
final_expression = expr_at_t0.subs(t, critical_point[0]) numerator, denominator = final_expression.as_numer_denom() p, q = sp.fraction(final_expression)
(p*q) % 10000
Simplify numerator/denominator, reduce fraction
p_numerator, q_numerator = numerator.p, denominator.p # Accessing via parts? print(f"{numerator}/{denominator}"), p, q
Correction
Final_val = numerator / denominator
p = Final_val.p q = Final_val.q
print(p + q)
More Accurate Code
Re-express correctly. Some errors present earlier; fixing accordingly.
