Prove that sec A cosec A - cotA= tan A.
Can someone’s please help me with this one.. I’ll give brainliest

see explanation

Step-by-step explanation:

Using the trigonometric identities

secx = , cosecx =

cotx = , tanx =

Consider the left side

secA cosecA - cotA

= × -

= -

=

= ( cancel sinA on numerator/ denominator )

=

= tanA = right side ⇒ proven

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
