please show work :) 5.Solve 3 sinº 8 tan 8 – 13 sinº 8 = 0 for exact solutions over the interval 6. Solve Triangle ABC, given that A = 47°32', b = 7956x c=115).
Solve for å by showing all the details. a) tan” x — 4 sinº x = 0 where 0 < x <a b) sec(sin-1 Væ2 – 1) c) In(x) – In(3x2 + 2) = ln(K)
1. Find vfor t> 0 if the circuit is in steady state at t 0 Ans: -4e2" (cos 2t +sin 2t) +4 Volts 2Ω 1 H -0 2Ω 1
Question 12 Find the derivative of the function f(x)= (in(cox) + sinº(x))2. • f'(x) = 12(In(cox) + sin?(x)) (3sin?x cosx – tanx) • f'(x) = 12(In(cox) + sin?(x))+(3sinx cos?x - tanx) o f'(x) = 12(In(cox) + sin(x))(3sinx cosx + tanx) o f'(x) = 12(In(cox) + sin}(x))^2(3sin?x cosx + tanx) A Moving to another question will save this response.
7. Show that sin. nx-zs -zsin sin’x+ 1 4 3 sin' x sinº x +...= 2 sin x 2+sin x for all x ER
The following equation can "clearly" be simplified: In{ lim{f(x)-- - (X-1'] +$}} + (sinº q + cos?q) + (sinºq + cos?q) = Ë cosh pV I – tanhº p 2" n=0 A random sample of 70 statisticians indicated that 51 know how to simplify it. A second random sample (independent from the first) indicated that 42 of 500 mathemagicians know how to simplify it. Is the proportion of mathemagicians who know how to simplify the equation different from 7%? Using...
1. cos 4 x-sinº x = cos 2x 6 6 2. sin x + COS x = 1-3sin ?x cos” x 3. cos 2x = 1-tanx 1+tanx 4. 2sinx cosx = cos(x-y) – cos (x+y)
8. 2 sinº x-3 sin x-1=0 11. 4 sin’ x + 7 sin x = 6 9. tanx-1=0 12. ( tan x-)(tan x-3) = 0
