A man on a top of a tower observes a truck at an angle of depression α where tanα = 1/√5 and sees that it is moving towards the base of the tower. Ten minutes later, the angle of depression of the truck is found to be β where tan β=√5, if the truck is moving at a uniform speed, determine how much more time it will take to reach the base of the tower...
10 minutes=600sec
Ans: Let the speed of the truck be x m/sec CD=BC-BD
In right triangle ABC
tanα = h/BC tanα = 1/√5
BC=h√5............. 1
In right triangle ABD
tanβ= h/BD
h=√5BD ( tan β=√5 )
CD=BC-BD ( CD=600x )
600x =5BD-BD BD=150x
Time taken = 150x /x
=150 seconds
Time taken by the truck to reach the tower is 150 sec.

Determine or find out if the subsequent series is convergent or divergent. If it converges find out its value. Solution To find out if the series is convergent we fir
Now we have to discuss the basic operations for complex numbers. We'll begin with addition & subtraction. The simplest way to think of adding and/or subtracting complex numbers is
In triangle ABC, if sinA/csinB+sinB/c+sinC/b=c/ab+b/ac+a/bc then find the value of angle A.
Solve 2 ln (√x) - ln (1 - x ) = 2 . Solution: Firstly get the two logarithms combined in a single logarithm. 2 ln (√x) - ln (x - l) = 2 ln ((√x) 2 ) ln (1 - x ) = 2
Partial Derivatives Partial derivatives are used while we want to investigate the effect of one independent variable on dependent variable. For illustration, the revenues of a
