1.	11. which of the following statement is true? 1) Sin thita = cos(90-thita) 2) cos thita = tan(90-thita) 3) Sin thita = tan (90-thita) 4) tan thita = tan(90 thita)
Answer» Answer: Step-by-step EXPLANATION: cos(90-theta)= sin(theta) sec(90-theta)= COSEC(theta) sin(90-theta)=cos(theta) tan(90-theta)=cot(theta) cot(90-theta)=tan(theta) cosec(90-theta)=sec(theta) so now GIVEN that substituting in given equation sin(theta)cosec(theta)tan(theta)/sec(theta)cos(theta)tan(theta) + cot(theta)/cot(theta) tan(theta)/tan(theta)= 1 since cosec(theta)=1/sin(theta) sec(theta)=1/cos(theta) sin(theta)* 1/sin(theta)/ 1/cos(theta)*cos(theta) + 1

11. which of the following statement is true? 1) Sin thita = cos(90-thita) 2) cos thita = tan(90-thita) 3) Sin thita = tan (90-thita) 4) tan thita = tan(90 thita)

Answer»

Answer:

Step-by-step EXPLANATION:

cos(90-theta)= sin(theta)

sec(90-theta)= COSEC(theta)

sin(90-theta)=cos(theta)

tan(90-theta)=cot(theta)

cot(90-theta)=tan(theta)

cosec(90-theta)=sec(theta)

so now GIVEN that substituting in given equation

sin(theta)cosec(theta)tan(theta)/sec(theta)cos(theta)tan(theta)

+ cot(theta)/cot(theta)

tan(theta)/tan(theta)= 1

since cosec(theta)=1/sin(theta)

sec(theta)=1/cos(theta)

sin(theta)* 1/sin(theta)/

1/cos(theta)*cos(theta)

+ 1
