evaluate ∫ (sqrt(x)( ax^2 + bx + c)) dx
 
 
∫ (sqrt(x)( ax^2 + bx + c)dx =​∫ (x^1/2(ax^2 +bx +c)dx =​∫ (ax^5/2 +bx^3/2 +cx^1/2)dx =2​ax^7/2 /7 +2bx^5/2 /5 +2cx^3/2 /3 +K {we know that​∫x^ndx =(x^(n+1) /(n+1)} Here K is...

Just change the expression in terms of sin and cos (i.e. sina+cosa and (sina)(cosa) ) Then replace sina.cosa as t and sina + cosa as (1+2t) 1/2 This gives value of t . we have to find sin 2a...

COS(A-B)/COS(A+B)+COS(C+D)/COS(C-D)=0 THEN SHOW THAT tan A tan B tan C tan D=-1
 
 
STEP1:COS(A-B)/COS(A+B)=(COS(A)COS(B)+SIN(A)SIN(B))/(COS(A)COS(B)-SIN(A)SIN(B)) SIMILARLY OPEN THE EXPRESSION FOR THE OTHER TERM. STEP2:DIVIDE NUMERATOR AND DENOMINATOR IN BOTH CASES BY...
