As ?
yes indeed.tan (a-b)= (tan a-tanb)/ (tana tanb)
but i think this is p3
I tried, but I sucked the whole P3yes indeed.
i did this formula in P3 along with it's derivation and similar addition formulas for sin and cos.
I see
Find the probability of R and S
Use the substitution u = sin 4x to find the exact value of cos^34x dx and the given range is (0 and 1/24pi)............Someone help me with this question.
du/dx =4cos4x
and for integration of cos^3 4x write as cos4x * cos^2 4x dx
I am ignoring the integration sign now onwards.
=(4cos4x)/4 * (1-sin^2 4x) dx
=du/dx (1-sin^2 4x)/4 dx (the dx is cancelled here)
so (1-u^2)/4 du (since sin4x = u)
Now the new limits for integration are found using u=sin (1/24 pi) and u = sin (0)
you can take the 1/ 4 outside the integration sing to give 1/4[1-u^2 du] (i used brackets for integration sign)
now integrate with respect to du and solve to get the final answer since we have changed the limits you dont have to change u back to x.
Your welcome brotherthanks, brother.
Can you Anawer my qYour welcome brother![]()
using the domainHow do i find the range of any given function, generally?
Hope this is legible:
